Lori Loughlin filed for divorce from Mossimo Giannulli on September 8, 2026, ending their nearly 30 year marriage. Court documents list August 31, 2025, as the couple's separation date and cite irreconcilable differences. Lori Loughlin and Mossimo Giannulli married in 1997 and share two daughters, Bella Rose Giannulli and Olivia Jade Giannulli. Their split became public in October 2025, when Loughlin's representative confirmed that the couple was living apart. What Happened to Their Marriage? The divorce filing follows the former couple's decision to list their Hidden Hills, California, home for sale months earlier. Loughlin and Giannulli purchased the property in August 2020, the same month they received sentences tied to their college admissions scandal convictions. John Stamos , Loughlin's Full House and Fuller House costar, has publicly supported her during the breakup. On a Good Guys podcast episode in October 2025, Stamos criticized Giannulli as a “terrible narcissist” and said the separation had deeply affected Loughlin, while neither Loughlin nor Giannulli has publicly explained the split.
