Lori Loughlin Files for Divorce From Mossimo Giannulli After 28 Years

Lori Loughlin has taken the final legal step to end her long-term marriage to Mossimo Giannulli. After living apart for roughly twelve months, the former *Full House* star formally submitted court paperwork to end her relationship with the fashion designer. According to legal documents filed on September 4, 2026, the actress cited irreconcilable differences as the grounds for ending the marriage. The paperwork indicates that the couple originally called it quits a year prior, specifying August 31, 2025, as their formal date of separation.

Why Did Lori Loughlin and Mossimo Giannulli Break Up?

Court filings confirm that the pair decided to permanently go their separate ways due to standard irreconcilable differences. The formal paperwork comes after nearly 28 years of marriage, bringing a quiet close to one of Hollywood’s most publicly examined unions. Reports indicate that the couple took their time navigating the breakdown of their partnership before making anything official with the court system. By establishing a separation date in late August 2025, the pair had already spent a full year living independent lives prior to submitting the formal filing in early September 2026.

Do Lori Loughlin and Mossimo Giannulli Have a Prenup?

The recent court documents confirm that financial assets and property arrangements will be handled according to a pre-existing legal contract. The paperwork specifies that the former couple signed a prenuptial agreement prior to tying the knot, which will govern how their marital assets and individual finances are divided moving forward. While the dissolution of a nearly three-decade union involves significant coordination, the presence of an established marital contract suggests that division of property will follow pre-determined guidelines. Neither party has issued a public statement beyond the contents of the official legal filings. With the court proceedings officially underway, Loughlin turns the page on a long chapter. After decades together and navigating high-profile life changes, the actress is officially closing out her marriage and stepping into her next chapter single.
