Lori's close friend and Full House co-star, John Stamos, accused Mossimo of being a "terrible narcissist" on the Good Guys podcast, and claimed that Lori "cleaned everything up" for her husband.
"I will never talk to him again," he declared. "Whatever he did to her, it busted her up to the core. And she put up with a lot over the years for this guy. I know a lot, and I was by her side through a lot of it."
Lori opened up about moving on from the major scandal in a 2024 interview with First For Women magazine. "I try to be a forgiving person. I'm not one to hold onto stuff. Stuff happens to everyone," she said.
"We've all been in positions to ask for forgiveness, but to ask for it, you have to learn and know how to give forgiveness, too. My family wasn't one to hold grudges. I didn't grow up in a household where if you made a mistake, you weren't forgiven."
She continued: "No one is perfect; we all make mistakes. So I was always told to let stuff go. And I think for your own health, you have to let things go because you can't hang on to negativity. Life's too short."
