Britney Spears' ex-husband Kevin Federline sat down with Access Hollywood to chat about his role on VH1’s Celebrity Fit Club: Boot Camp, and the former fattie reveals that depression played a big part in his overeating.

K-Fed told the show, "Once you get depressed, you don’t really feel like doing anything. You’re kind of discouraged about yourself and then the weight gain too, or that makes me more depressed. I mean, it’s a combination of all of those things.”

Kevin admitted that his divorce from Britney in 2006 played a large part in his depression, and while he doesn't blame her entirely, he definitely seems to be using it as an excuse! “A number of things between, I mean, everybody knows what happened with me and Brit. I’m not going to say that’s the total cause of it but, I mean, just not being happy with myself was probably the main part of my depression,” he said.

So what's his relationship with Britney like now? “I’m in the best possible scenario right now," Kevin says. "I’m really happy for her. I’m very happy for her.”

Kevin definitely seems to be happier with fewer pounds on his frame, and he tells Access that being asked to join Celebrity Fit Club couldn't have come at a better time. “They called me and they asked me if I wanted to do it and I had maybe 24 hours to decide because the show started taping the next day after that weekend,” he said. If you want to watch K-Fed shed the pounds, be sure to watch the show when it premieres on February 8, 2010!
