‘Full House’ Fans React After John Stamos Rips Into Lori Loughlin’s Ex Mossimo Giannulli

John Stamos is sticking by his former Full House co-star and onscreen wife, Lori Loughlin, amid her separation from her soon-to-be ex-husband, Mossimo Giannulli.

Appearing on the Good Guys podcast on Monday (October 20), Stamos was asked about Loughlin and Giannulli, who earlier this month confirmed they are splitting up after 28 years of marriage. The ER alum didn’t hold back, expressing his heartache for Loughlin and referring to Giannulli as a “narcissist.”
