For almost three decades, Lori Loughlin and fashion designer Mossimo Giannulli remained married through intense public scrutiny, a high-profile criminal case and separate prison sentences. Now, a new legal filing has formally changed the status of their relationship.
The Full House actress has filed for divorce, nearly a year after the couple confirmed they were living apart. The filing brings a long-running period of uncertainty into the courts, while leaving some of the most private questions about the end of their marriage unanswered.

Lori Loughlin officially files for divorce
Loughlin, 62, filed a petition for dissolution of marriage in Los Angeles Superior Court on September 4, 2026, according to court documents reported by multiple outlets.
The filing lists August 31, 2025, as the date the couple separated and cites “irreconcilable differences” as the legal reason for ending the marriage.
Loughlin and Giannulli, 63, married on November 27, 1997. That means they had been married for almost 29 years when the divorce paperwork was filed.
Importantly, the petition does not identify a specific incident as the cause of the breakup. Instead, it uses the standard legal language of irreconcilable differences.
The couple’s separation had already become public nearly a year earlier.
In October 2025, Loughlin’s representative Elizabeth Much confirmed that the two were no longer living together. At the time, Much said they were:
“living apart and taking a break from their marriage.”
She also made clear that there were no divorce proceedings underway at that point:
“There are no legal proceedings at this time.”
Almost one year later, that situation has changed.

Their prenuptial agreement could shape the financial proceedings
While the emotional and personal reasons behind the split remain largely outside the public court record, Loughlin’s petition does provide important information about how financial matters could be handled.
According to the filing, Loughlin and Giannulli signed a premarital agreement in October 1997, shortly before their wedding. That agreement was later amended in August 2015.
Loughlin’s petition asks for their property, assets and debts to be handled according to the terms of those premarital agreements.
However, the specific financial provisions contained in the original agreement and its 2015 amendment have not been publicly disclosed in reporting surrounding the divorce filing.
The petition also asks that the issue of spousal support be “reserve[d] for future determination.” In other words, the matter has not been conclusively settled in the initial filing.
Attorney’s fees and costs are also addressed. The petition asks the court to determine relevant financial issues according to the parties’ agreements.
The filing states:
“Respondent respectfully requests that, with respect to any issue submitted to the Court for determination, the Court include in the Statement of Decision any and all calculations upon which the determination of any issues made, including but not limited to, spousal support, property characterization, credit and reimbursements, property division, tax consequences and attorneys’ fees and costs.”
At this stage, there is no publicly established final division of the couple’s assets. The precise terms of their private agreements also remain undisclosed.

Lori Loughlin and Mossimo Giannulli have two adult daughters
The couple share two daughters: Isabella Rose Giannulli, commonly known as Bella, and Olivia Jade Giannulli.
Both have become publicly recognizable in their own right. Olivia Jade, in particular, built a career as a social media personality and influencer.
Because both daughters are adults, the divorce filing does not indicate any custody dispute.
Their family life, however, has previously been at the centre of enormous public attention.

The college admissions scandal became a defining chapter
Loughlin and Giannulli became two of the most recognizable names connected to the 2019 college admissions scandal, commonly known as Operation Varsity Blues.
Federal prosecutors accused the couple of paying admissions consultant William “Rick” Singer and using fraudulent methods to help secure their daughters’ admission to the University of Southern California.
The scheme involved falsely presenting their daughters as crew recruits even though they were not competitive rowers.
After months of legal battles during which the couple initially maintained their innocence, Loughlin and Giannulli ultimately pleaded guilty to federal conspiracy charges in 2020.
The couple admitted to paying $500,000 connected to the scheme.
The legal consequences were substantial.
Loughlin was sentenced to two months in federal prison, while Giannulli received a five-month sentence. Loughlin was also ordered to pay a $150,000 fine and complete 100 hours of community service.
Giannulli received a $250,000 fine and 250 hours of community service.
Loughlin was released from prison in December 2020, while Giannulli completed his sentence in 2021.
Multiple reports have described the admissions scandal as a major source of strain on the marriage. However, that distinction matters: neither the divorce petition nor a public statement from Loughlin identifies the admissions case as the legal reason for their divorce.

What Loughlin and Giannulli admitted in court
Later commentary about the couple’s breakup has sometimes portrayed Loughlin as having played little or no role in the admissions scheme. The established legal record is more nuanced.
Federal prosecutors previously described Giannulli as the more active participant, but prosecutors also said Loughlin was involved in the scheme.
Loughlin herself pleaded guilty to conspiracy and acknowledged at her 2020 sentencing that she had made a serious mistake.
She apologized for her conduct and said she had:
“made an awful decision”
and
“allowed myself to be swayed from my moral compass.”
Giannulli also expressed remorse at sentencing, saying he took:
“full responsibility”
for his actions.
Those guilty pleas and sentencing statements remain part of the established public record.
They are particularly important when separating confirmed legal facts from later opinions and commentary about what happened inside the marriage.

John Stamos publicly defended Lori Loughlin
As news of Loughlin and Giannulli living separately emerged in 2025, Loughlin’s longtime Full House co-star John Stamos publicly weighed in on the situation.
During an appearance on the Good Guys podcast in October 2025, Stamos strongly defended Loughlin and sharply criticized Giannulli.
Discussing his decades-long friendship with Loughlin, Stamos said:
“This woman’s a saint,”
He also described Giannulli as:
“a terrible narcissist”
and added:
“I will never talk to him again.”
Stamos further argued that Loughlin had been unfairly affected by the admissions scandal, saying:
“She didn’t deserve to be dragged through that… I know for a fact it was all him.”
He also discussed Loughlin’s prison experience, saying:
“She goes to f—ing prison for this a–hole for three months, right? And he goes for whatever.”
Those comments represent Stamos’ personal view and should not be treated as an official finding about Giannulli’s legal responsibility beyond the facts established through the criminal case.
Court records established that both Loughlin and Giannulli pleaded guilty and were sentenced in connection with the admissions scheme.

The couple had already been living separate lives
Although their separation was not publicly announced until October 2025, Loughlin’s divorce petition identifies August 31, 2025, as the official separation date cited in the filing.
That creates a nearly one-year period between the listed separation date and the divorce filing.
The petition itself does not provide a detailed narrative explaining what ultimately caused the marriage to collapse.
Instead, the legal filing states irreconcilable differences, while the more private reasons behind the breakup remain largely outside the publicly documented court record.
For now, the legal process offers a clearer picture of the procedural situation than it does of the couple’s personal relationship.

Loughlin returned to the public spotlight before the divorce filing
The divorce filing also arrives during a period in which Loughlin has increasingly returned to public life following years of reduced visibility.
In August 2026, she returned to Instagram after a lengthy absence and shared photographs and videos involving her family, friends and former Full House colleagues.
Her social media return came shortly before news of the divorce became public.
One recent post included the caption:
“Here’s to things working out.”
The timing attracted attention because the post appeared shortly before the divorce filing emerged. However, there is no confirmation that the caption was specifically referring to her marriage or to the impending legal proceedings.
Loughlin has also continued rebuilding her acting career following the admissions scandal, gradually returning to television and film projects.

A nearly 29-year marriage now moves into the courts
Loughlin and Giannulli’s divorce represents the end of a marriage that began in 1997 and continued through some of the most turbulent years of their lives.
Their relationship survived years of public scrutiny surrounding Operation Varsity Blues, criminal proceedings, guilty pleas, separate prison sentences and intense media attention.
But the public record does not provide a detailed explanation for why the marriage ultimately ended.
What is established is straightforward: Loughlin filed for divorce in Los Angeles on September 4, 2026. She lists August 31, 2025, as the date of separation and cites “irreconcilable differences” as the legal grounds.
The petition also points to a premarital agreement signed in October 1997 and amended in August 2015. Property, assets, debts, spousal support, tax consequences and attorney’s fees are among the financial matters addressed in the filing, with the precise terms of the private agreements still undisclosed.
The couple’s two daughters, Bella and Olivia Jade, are adults, so the filing does not indicate a custody dispute.
For now, the divorce process formally closes another chapter in a complicated relationship, while the court proceedings will determine the financial and property issues that remain.

Conclusion
Lori Loughlin’s September 4, 2026 divorce filing marks a formal turning point after nearly 29 years of marriage to Mossimo Giannulli. The couple had already been living separately for months, but the new court action moves their relationship from a publicly acknowledged break to an official dissolution proceeding.
The filing confirms the separation date, cites irreconcilable differences and references their long-standing premarital agreements, while leaving the private reasons for the breakup largely unexplained. After years defined by marriage, family, public scrutiny and the consequences of Operation Varsity Blues, Loughlin and Giannulli now face the next chapter through the courts.
