On Sunday during The Real Housewives of Orange County panel at BravoCon — the network’s first-ever convention — Shannon, 55, said that her daughters, Sophie, 18, and twins Stella and Adeline, 14, were “horrified” after seeing a nude photo of their dad and his new girlfriend on Instagram.
“My kids all saw it at school,” Shannon said, adding of David, “To each his own, he can do whatever he wants to do.”
In response, David tells PEOPLE, “My kids called and we laughed at the selfies Lesley posted. It’s amazing how much Shannon talks about me and my life. She needs some peanut butter to go with her jelly.”
Shannon and David, 54, split in September 2017 after over 17 years of marriage and settled their divorce in April 2019. While things between Shannon and David might be rocky, the Bravo star said she and her new boyfriend, John Janssen, are stronger than ever.
“He’s just a great person,” Shannon said. “If I were to make a list of the perfect person for me, he has all those attributes. You see it in movies and you think it’s not real. I’ve never been happier.”
Shannon also revealed that her ex-husband has yet to meet her new man.
“It’s strange. I tried to introduce him to John, but he walked away,” Shannon said.
“There’s a lot of anger still,” she said of her former husband. “But I can’t control him.”
When asked at the panel how the show affected her breakup, Shannon stressed, “I would have been divorced earlier,” adding, “Being on the show gave me more motivation to stay together. Maybe when I found out about the affair, I would have gone. I don’t know.”
BravoCon ran from Friday through Sunday across three venues in the Big Apple: The Manhattan Center (311 W 34th St), Skylight Modern (537 W 27th St) and Union West (535 W 28th St).
