*EXCLUSIVE* Rebecca Romijn and Jerry O'Connell get Quality Family Time with their Girls

During a Wednesday appearance on Bravo’s Watch What Happens Live, actor Jerry O’Connell recalled a funny story about telling his daughters – 6-year-old twins Dolly and Charlie – that their mother, model-actress Rebecca Romijn, was once married to Uncle Jesse from Full House.

“Full House is on a continual loop,” he said. “Because they expressed, like, real feelings for the character of Uncle Jesse, I said, ‘You know girls, I gotta tell you something. This is gonna be crazy.’ “

The We Are Men actor, 41, went on to show the girls photos of mom with her ex-husband, actor John Stamos.

“You know, I showed them photos on the Internet of their wedding. And you were there,” he said to Lori Loughlin, who was also a guest on the show.

He added: “And it was a beautiful ceremony. And my kids really want to know why mom isn’t still with him. ‘That was a mistake, Mom.’ ”

Host Andy Cohen went on to ask O’Connell about Giuliana Rancic‘s claims that he cheated on her during their courtship.

“We dated, and then we didn’t date, and I was in the book. I didn’t think that much of it. She’s a very nice girl,” O’Connell said of Rancic.

He added: “I don’t want to say anything negative. She’s a very nice girl. We had a very fun time. It was decades ago. I don’t believe cell phones were used then. It was like horse and buggy! It was a while ago.”
