Stamos Slams Loughlin's Ex-Husband Giannulli as 'Terrible Narcissist'

In the wake of Lori Loughlin's separation from her husband of 27 years, Mossimo Giannulli, the actress's longtime friend and co-star John Stamos has spoken out with strong words against Giannulli.

Last month, on the Oct. 20 episode of the Good Guys podcast, Stamos did not hold back in his assessment of Giannulli, calling him a "terrible narcissist" and stating that he will never talk to him again. Stamos, who starred alongside Loughlin on the hit shows Full House and Fuller House, expressed deep heartbreak for his friend of 40 years, saying that "whatever he did to her, it busted her up to the core."

Stamos emphasized that Loughlin, whom he describes as a "good person, a good mother, a good wife," has endured a lot over the years with Giannulli. "I know she's just devastated," Stamos said, "and for a girl who has lived her life really well, to be thrown into, now, this separation exploding, blowing up her family this way. And I just hate to see her go through this."

Despite the turmoil, Loughlin was recently spotted out for dinner with actor James Tupper, her co-star from the TV series Men in Trees. The two appeared to be offering each other support during this difficult time for the Full House star.
