Lori Loughlin filed for divorce from Mossimo Giannulli on Friday, Sept. 4, moving to end nearly 30 years of marriage. The filing cites irreconcilable differences and puts a formal legal step behind a split that had already been playing out in public.

The divorce petition lists Aug. 31, 2025 as the date of separation, even though the filing came on Sept. 4. Loughlin and Giannulli have a prenuptial agreement that covers separate and community property, and the issue of spousal support will be handled later. That leaves the immediate legal work centered on the terms of the marriage, not a public fight over the reason for the breakup.
They have been married since November 1997 and share daughters Olivia Jade Giannulli and Isabella Rose Giannulli. The filing lands after a long stretch in which the couple’s private life was already under scrutiny, and after their involvement in the Varsity Blues college admissions scandal.
Varsity Blues college admissions scandal
In 2019, Loughlin and Giannulli were charged in the Varsity Blues college admissions scandal after admitting they paid half a million dollars to get both daughters into the University of Southern California as crew recruits. Loughlin pleaded guilty to conspiracy to commit wire and mail fraud, while Giannulli pleaded guilty to conspiracy to commit wire and mail fraud and honest services wire and mail fraud.
Loughlin served two months in prison in late 2020, and Giannulli served a five-month sentence that began in November 2020 before he was released on home confinement in April 2021. A publicist said in October that they were living separately, which made the Sept. 4 filing less a surprise than the formal paperwork that finally set the separation on record.

Olivia Jade Giannulli and Isabella Rose are directly affected by the filing, because the marriage that shaped their public family identity is now moving through divorce court. Loughlin’s return to acting in 2021 and her later reappearance on social media on Aug. 31 showed she had begun rebuilding a public life; the divorce turns that private reset into a legal one.
The practical next step is spousal support, which the filing says will be decided later. After nearly 30 years together, the case now looks less like a breakup headline than a property and support proceeding with two daughters and a long paper trail already attached to it.
