"The story is not true, and I’m not going to comment [further] on it," the Lost star says in a new interview for Playboy's May issue.
Fox, 43, says he and his wife bring out the best in each other. "Margherita and I have been best friends and best lovers," he says. "She's the love of my life."
What makes their relationship work?
"We have managed to both be intensely independent and maintain that strength in our relationship," he says. "I am a man, and I am an appreciator of women. At the same time, Margherita is the s---. I can honestly say we're good together."
And their union has stood the test of time. Says Fox: "We've been together for 23 years, so let's leave it at that."
Once Lost wraps for good, Fox and his family – including daughter Kyle and son Byron – plan to relocate to somewhere a little less tropical than Hawaii, where the hit ABC show films. "I miss having four seasons," Fox, who plans to move to Oregon, says. "My brothers are two of my closest friends in the world. I want to spend time with them and my mother while I can. I want our two kids to be close to their first cousins."
Of course the transition to the mainland won’t be easy.
"It will be hard for the kids to leave their friends in Hawaii," he says. "They love it here, but with all respect to the good people of Hawaii who've been so good to us, I can't wait to leave."
