Lori Loughlin Divorce Ends Her 29-Year Marriage
Lori Loughlin divorce proceedings are officially underway, bringing the actress’s nearly three-decade marriage to fashion designer Mossimo Giannulli closer to a legal conclusion.
The “Full House” star filed a petition to dissolve the marriage in California on Friday, Sept. 4, according to court documents cited by multiple U.S. entertainment outlets. Loughlin reportedly identified Aug. 31, 2025, as the couple’s official date of separation and listed irreconcilable differences as the reason for the split.
The filing follows nearly a year of public speculation about the future of the marriage. In October 2025, Loughlin’s representative confirmed that she and Giannulli were living apart, but emphasized at the time that no legal proceedings were underway.
That situation has now changed.
The divorce petition makes the couple’s breakup a matter of court record after a marriage that lasted almost 29 years and endured intense public scrutiny, family challenges and the fallout from the nationwide college admissions scandal.
Lori Loughlin Files for Divorce From Mossimo Giannulli
Loughlin, known to generations of television viewers for playing Aunt Becky on “Full House” and its Netflix continuation “Fuller House,” married Giannulli on Nov. 27, 1997.
According to reports based on the filing, the actress petitioned for a dissolution of marriage shortly before Labor Day weekend. The documents state that the pair separated on Aug. 31, 2025—more than a year before news of the filing became public.
The Mossimo Giannulli divorce case is not expected to involve child custody because the couple’s two daughters, Isabella “Bella” Rose Giannulli and Olivia Jade Giannulli, are adults.
Instead, the most important legal questions are likely to center on property, financial obligations and how the couple’s prenuptial agreement will be interpreted.
Loughlin reportedly asked the court to reserve the question of spousal support for future determination. This means the issue has not necessarily been waived or resolved. It may be addressed later through negotiations, a settlement or additional court proceedings.
Representatives and attorneys for Loughlin and Giannulli had not publicly commented on the filing when the initial reports were published.
What the Divorce Filing Reveals
Court documents cited by Fox News and E! News offer several important details about the breakup.
The Couple Separated in August 2025
Loughlin listed Aug. 31, 2025, as the date of separation. That date is significant because it can help determine when the marital partnership legally ended and which assets or debts may be classified as separate or community property under California law.
The reported separation date also aligns with the timeline disclosed publicly in October 2025. At that point, Loughlin’s representative said the couple was living apart but had not started formal legal proceedings.
The approximately one-year gap between the Lori Loughlin separation and the divorce filing suggests that the estranged spouses had time to evaluate their next steps before moving the case into court.
It remains unknown whether the two have already negotiated a private settlement or whether major financial questions remain unresolved.
Loughlin Cited Irreconcilable Differences
The divorce petition lists irreconcilable differences as the legal basis for ending the marriage.
This is common in California no-fault divorce cases. The phrase does not identify a specific allegation or assign legal blame to either spouse. Instead, it indicates that the marriage has suffered a breakdown that cannot be repaired.
Neither Loughlin nor Giannulli has publicly provided a detailed personal explanation for the split. Responsible coverage should therefore distinguish between information contained in court records, comments attributed to named individuals and unverified speculation about the former couple’s private life.
Spousal Support Has Not Been Decided
Loughlin reportedly requested that the issue of spousal support be reserved for a later decision.
That language leaves several possibilities open. The parties could reach an agreement outside court, seek a judicial determination or ultimately decide that no support should be paid.
The filing does not establish how much support, if any, either spouse might receive. It also does not reveal the complete financial terms of the couple’s prenuptial agreement.
Why Reserving Support Matters
Reserving jurisdiction gives the court the ability to address support later rather than closing the issue immediately.
In a long-term marriage involving substantial careers, business interests and valuable assets, the financial picture can require extensive disclosure. Attorneys may need time to evaluate income, investments, property ownership, tax consequences and obligations created during the marriage.
That process can continue even when both spouses agree that the marriage itself should end.
The Lori Loughlin Prenuptial Agreement
One of the most closely watched elements of the case will be the Lori Loughlin prenuptial agreement.
Reports indicate that Loughlin and Giannulli signed a prenup in October 1997, approximately one month before their wedding. In her filing, Loughlin reportedly identified certain assets and debts as separate property under that agreement.
She also asked the court to determine the parties’ rights concerning community property in accordance with the prenup.
A prenuptial agreement can establish how specific assets, earnings or debts will be treated if a marriage ends. However, simply confirming that an agreement exists does not explain its full impact.
The complete document has not been publicly detailed in the reports, and it would be premature to conclude which spouse benefits most from its provisions.
What Could Be at Stake Financially?
Giannulli built the Mossimo clothing brand, which became widely recognized through its long-running relationship with Target. Loughlin, meanwhile, developed a television and film career spanning several decades.
Their financial history may include real estate, investments, entertainment income, business proceeds and other assets acquired both before and during the marriage.
Fox News reported that the filing asks for calculations related to issues that may be presented to the court, including property classification, reimbursements, division of assets, taxes and legal costs.
These requests do not necessarily mean that a courtroom battle is inevitable. Divorce petitions often preserve a party’s legal options while attorneys work toward a negotiated resolution.
A Marriage That Lasted Nearly Three Decades
Loughlin and Giannulli married in 1997, making their relationship one of Hollywood’s longer-lasting marriages.
The actress was already widely recognizable from “Full House,” while Giannulli had established himself in the fashion industry. Their family later became familiar to a younger online audience through Olivia Jade’s work as a social media personality and content creator.
For years, Loughlin and Giannulli maintained a relatively private public image. That changed dramatically in 2019 when they became involved in the federal investigation known as Operation Varsity Blues.
The scandal placed the couple and their daughters at the center of a national debate about privilege, college admissions and access to elite universities.
How the College Admissions Scandal Changed Their Public Story
Federal prosecutors accused Loughlin and Giannulli of paying $500,000 to facilitate their daughters’ admission to the University of Southern California as purported crew recruits, despite neither daughter being a competitive rower.
The couple initially fought the charges but later entered guilty pleas in 2020.
Loughlin pleaded guilty to conspiracy to commit wire and mail fraud. She received a two-month prison sentence, along with a fine, community service and supervised release. Giannulli pleaded guilty to conspiracy to commit wire and mail fraud and honest-services wire and mail fraud. He received a five-month prison sentence and additional penalties.
Loughlin was released from federal custody in December 2020, while Giannulli completed his sentence in 2021.
The scandal became a defining chapter in their public lives. However, the divorce filing does not identify the criminal case as the legal reason for the split. The petition cites only irreconcilable differences.
Any claim that the admissions scandal directly caused the divorce would therefore go beyond the confirmed information currently available.
Loughlin’s Return to Acting
After serving her sentence, Loughlin gradually returned to television.
She reprised her role as Abigail Stanton in “When Hope Calls,” a spinoff connected to the Hallmark drama “When Calls the Heart.” Her comeback attracted attention because she had largely stepped away from public life following the admissions case.
Her career remains closely associated with “Full House,” where she appeared alongside John Stamos, Bob Saget, Candace Cameron Bure, Jodie Sweetin, Dave Coulier and other members of the long-running ensemble.
Entertainment audiences following Loughlin’s latest chapter may also be interested in Hannah Waddingham’s latest shows, career and upcoming projects, another look at how established television performers navigate evolving careers.
John Stamos Publicly Defended Lori Loughlin
John Stamos, Loughlin’s longtime “Full House” colleague and friend, discussed the separation during an October 2025 appearance on the “Good Guys” podcast.
Stamos strongly defended Loughlin and criticized Giannulli while describing the emotional effect of the breakup on his friend. He said he believed Loughlin was devastated by the separation and praised her as a mother, spouse and friend.
Stamos also offered his personal interpretation of the college admissions scandal and Giannulli’s role in it.
His comments attracted headlines, but they represent Stamos’ personal account rather than a court finding about the marriage. Giannulli did not publicly respond to those remarks in the reports reviewed for this story.
That distinction is particularly important in a developing divorce case. Comments from friends can provide context about personal relationships, but they do not establish the legal facts that will determine support or property division.
What the Divorce Means for Bella and Olivia Jade
Loughlin and Giannulli’s daughters are adults, so the case will not include a conventional child-custody dispute.
Bella and Olivia Jade nevertheless remain important members of the family affected by the separation. Both faced major public attention during the college admissions scandal, although federal prosecutors did not charge either daughter.
Olivia Jade later spoke publicly about the controversy and returned to social media and entertainment projects. Bella has generally maintained a lower public profile.
Neither daughter is required to comment on the divorce, and neither should be expected to explain decisions made by their parents.
The absence of custody litigation may make the legal process less complicated than a divorce involving minor children. Still, the emotional consequences of ending a decades-long marriage can extend throughout an adult family.
Their Hidden Hills Home and Changing Lives
Before the divorce filing, Loughlin and Giannulli reportedly listed their Hidden Hills, California, home for sale.
The property had been purchased in 2020, the same year the couple was sentenced in the college admissions case. Its listing fueled speculation that significant changes were occurring behind the scenes.
A real estate sale can have many explanations, and listing a home does not by itself prove that a couple is divorcing. In this case, however, it became part of a broader timeline that included living separately, confirmation of the split and the eventual filing.
Questions about the home’s proceeds and other real estate assets may be addressed under the prenuptial agreement or through California property law.
Why the Story Is Attracting National Attention
The Full House star divorce combines several elements that consistently draw public interest: a famous television performer, a long Hollywood marriage, substantial financial questions and a family that previously faced a major national scandal.
Loughlin remains strongly connected to “Full House,” a series that has retained an audience through syndication and streaming. Giannulli’s fashion career also gives the story significance beyond the entertainment industry.
Their nearly 29-year marriage survived career changes, parenting in the public eye, criminal prosecution and time in federal prison. The fact that the relationship ultimately ended after those events makes the filing especially notable to longtime followers.
Even so, the public record provides only a limited view of their private relationship. Neither spouse has issued a comprehensive statement explaining what happened inside the marriage.

What Happens Next in the Divorce Case?
The filing begins the formal legal process, but it does not reveal how quickly the divorce will be resolved.
Giannulli will have an opportunity to respond to the petition. The parties may then exchange financial disclosures and negotiate matters involving support, property and legal expenses.
Possible Settlement Negotiations
Many high-profile divorces are resolved through confidential negotiations rather than a public trial.
A settlement could determine:
Whether either spouse receives support
How real estate and investments are divided
Which assets qualify as separate property
Whether reimbursements are owed
How taxes and professional fees are handled
How the prenuptial agreement applies to disputed property
If the parties agree on all major terms, they can submit a settlement for court approval. If disagreements remain, a judge may be asked to resolve them.
Privacy Could Be a Priority
Given the scrutiny Loughlin and Giannulli experienced during the admissions scandal, both may have an interest in keeping the divorce as private as possible.
However, court filings can still produce new public information, particularly if disputes arise over the enforceability or interpretation of the prenup.
The filing does not currently establish whether the divorce will be amicable, contested or resolved through mediation.
No Public Claims of a New Romance
The available court documents do not identify infidelity, a new relationship or another specific event as the cause of the breakup.
Reports about celebrity divorces frequently generate unsupported theories on social media. In this case, the verified legal explanation remains irreconcilable differences.
Unless Loughlin, Giannulli or their authorized representatives provide additional information, claims about private conduct should be treated cautiously.
This is particularly important because Stamos’ public criticism of Giannulli may encourage speculation. His comments reflect his perspective as Loughlin’s friend, not an official finding in the divorce case.
Lori Loughlin Begins a New Chapter
The Lori Loughlin divorce filing marks a major turning point for an actress whose public life has included television success, family fame, legal controversy and a carefully managed return to entertainment.
After separating in August 2025, Loughlin has now taken the formal step required to end the marriage. The case will likely focus on the couple’s prenuptial agreement, property rights and the unresolved question of spousal support.
For Giannulli, the proceedings could also determine how business-related and personal assets are characterized after almost three decades of marriage.
The filing confirms the end of the relationship, but many details remain private. Neither party has publicly explained the underlying personal reasons for the split, and the court has not yet resolved the financial issues identified in the petition.
The story will continue to develop as Giannulli responds and the parties move through California’s divorce process.

For now, the central facts are clear: Loughlin and Giannulli separated on Aug. 31, 2025; Loughlin filed for divorce in September 2026; the stated reason is irreconcilable differences; and a prenuptial agreement is expected to play an important role in determining what comes next.
