Fueled by what the "Full House" alum described as "irreconcilable differences," Loughlin, 62, filed for divorce on Tuesday, Sept. 8, according to TMZ.
Loughlin reportedly listed their date of separation as Aug. 31, 2025, and revealed that she and Giannulli have a prenuptial agreement.
USA Today reported in October that the two were living separately, but no legal action had been taken.
Despite nearly three decades of marriage, the split does not come as a shock to those within Loughlin and Giannulli's friend group.
"People around Lori and Mossimo have known they have been going through a really hard time in the last year," a source told Us in October 2025. "This isn't a shock to people around them. It has been a rough time for Lori. She is devastated."
Full House Star Takes Step to End 28-Year Marriage
The former couple has been married since 1997. They share daughters Olivia Jade Giannulli, 26, and Isabella Rose Giannulli, 27.
Loughlin rose to fame with her role as Aunt Becky on the acclaimed series Full House between 1988 and 1995. She's also had a starring role in the Netflix reboot, Fuller House.
She also starred in Summerland, while making appearances in Curb Your Enthusiasm, Blue Bloods and 90210.
Giannulli is an American fashion designer who founded the clothing brand Mossimo. In 2000, the clothing brand signed a $27 million licensing agreement with Target.
News of Loughlin and Giannulli's split comes six years after the couple was indicted in the infamous Varsity Blues scandal.
In 2019, former USC soccer coach Laura Janke pleaded guilty to creating fake athletic profiles for wealthy celebrities' children. Prosecutors contend Janke created a fake athletic profile for Loughlin and Giannulli's daughter Olivia Jade.
According to court documents, Loughlin and Giannulli allegedly paid half a million dollars for their daughters to participate in the University of South Carolina athletics, despite them having no athletic background.
Giannulli was released on $1 million bail on March 12, 2019, according to court filings. Loughlin was released on $1 million bail the next day, an FBI spokesperson told the Associated Press.
