Lori Loughlin Files for Divorce After 28 Years

Lori Loughlin has formally filed for divorce from fashion designer Mossimo Giannulli, turning the couple’s long-running separation into a legal proceeding after 28 years of marriage. The filing is the clearest public step yet in a breakup that their representative acknowledged last fall.

Lori Loughlin divorce filing details

Court documents reviewed by E! News and Page Six say the Full House actor filed the paperwork on September 4 and cited irreconcilable differences. The documents list August 31, 2025, as the separation date. Neither outlet had received a response from the former couple’s lawyers when their reports were published.

The paperwork also references a prenuptial agreement signed in October 1997 and amended in August 2015. According to Page Six’s account of the filing, Loughlin asked for spousal support to be decided later and requested that property, assets and debts be divided under that agreement. She also asked that Giannulli cover her legal fees.

A marriage already lived apart

Loughlin and Giannulli married in 1997 and have two adult daughters, Isabella Rose and Olivia Jade. A representative confirmed in October 2025 that the pair were living separately. Their Hidden Hills home had also been placed on the market earlier that year, another visible sign that their shared household was changing.

The couple’s public history has remained closely tied to the college-admissions scandal. Both pleaded guilty in 2020 to federal conspiracy charges connected to payments intended to secure their daughters’ admission to the University of Southern California as purported crew recruits. Loughlin served two months in federal prison, while Giannulli served five months.

The divorce filing does not include minor-child custody questions because both daughters are adults. It does, however, open a new phase for a couple whose separation had previously been communicated through a representative rather than a court case. For now, the filing records Loughlin’s requests; it does not establish how property or support will ultimately be resolved.
