Actress Lori Loughlin has officially filed for divorce from fashion designer Mossimo Giannulli, bringing an end to one of Hollywood’s long-standing marriages after nearly 28 years together.
Court records filed in Los Angeles Superior Court show that Loughlin submitted divorce documents on September 4, citing irreconcilable differences as the reason for ending the marriage. The filing provides new details about the couple’s separation and confirms that they had been living apart for more than a year before taking legal steps to dissolve their relationship.
According to the court documents, Loughlin listed August 31, 2025, as the official date of separation. The date offers a clearer timeline of the couple’s split and indicates that they had already ended their shared life together before reports of marital difficulties became public.
News of the separation first emerged in October 2025, when representatives confirmed that Loughlin and Giannulli were living apart and taking a break from their marriage. At that time, no divorce proceedings had been initiated, and both parties appeared to be evaluating the future of their relationship.
The newly filed documents reveal that the separation had actually begun more than a month earlier. The timeline suggests that the couple spent over a year separated before deciding to formally end their marriage.
Loughlin, 62, and Giannulli, 63, were married on November 27, 1997. During their nearly three decades together, they became one of the entertainment industry’s most recognizable couples. They share two daughters, Isabella Rose Giannulli and Olivia Jade Giannulli, both of whom are now adults.
Because their children are no longer minors, the divorce filing does not include any requests related to child custody or child support. Instead, the legal process is expected to focus primarily on financial matters and the division of assets.
One notable detail in the filing concerns the couple’s premarital agreement. Documents show that Loughlin and Giannulli signed a prenuptial agreement in October 1997, shortly before their wedding. The filing also reveals that the agreement was amended in August 2015.
Loughlin is asking the court to divide property, debts, and other financial interests according to the terms outlined in both the original agreement and its later amendment. The filing leaves questions regarding spousal support to be addressed at a later stage in the proceedings.
The amendment to the prenuptial agreement predates one of the most challenging periods in the couple’s public life. In 2020, both Loughlin and Giannulli pleaded guilty to federal conspiracy charges connected to the college admissions scandal that attracted nationwide attention.
Prosecutors alleged that the couple paid $500,000 to help secure admission opportunities for their daughters by presenting them as athletic recruits. As part of plea agreements, both accepted responsibility and served prison sentences. Loughlin served two months, while Giannulli served five months.
The case placed significant pressure on the family and led to years of public scrutiny. Despite rebuilding their public and professional lives after the scandal, questions about the state of their marriage emerged several years later.
Neither Loughlin nor Giannulli has publicly discussed in detail the reasons behind their separation. Representatives for both have largely remained private regarding the circumstances that led to the breakdown of the relationship.
Interest in Loughlin’s personal life increased again in August 2026 when she returned to Instagram after an absence of approximately seven years. Her comeback featured a nostalgic reunion with several former cast members from the popular television series Full House.
The video included appearances from John Stamos, Jodie Sweetin, Candace Cameron Bure, Andrea Barber, Scott Weinger, and Dave Coulier. The group recreated the well-known “Wake Up, San Francisco” introduction associated with Loughlin’s character, Rebecca Donaldson, also known as Aunt Becky.
Loughlin captioned the post with a simple message welcoming herself back to social media. Notably, her return occurred exactly one year after the separation date listed in the divorce filing.
With the legal process now underway, the filing formally closes a chapter in a marriage that lasted nearly three decades. While financial matters remain to be resolved, the court documents confirm that the couple’s separation has evolved into a permanent decision to move forward independently after many years together.
