K-Fed Battles The Bulge

Since his split with Britney Spears, Kevin Federline has been all over tabloids and magazines because of his extreme weight gain. The former back-up dancer used to be trim and fit, but in recent months he is looking less and less like his old self.

Although there have been rumors about K-Fed starting his own reality show, he has been confirmed as a participant on the seventh season of VH1's "Celebrity Fit Club," according to MTV.com.

Federline won't be a stranger to everyone on "Fit Club," though. His ex-girlfriend and the mother of two of his kids, Shar Jackson, will also be on the weight-loss show. Other stars that will be appearing include Nicole Eggart of "Baywatch" fame and Whitney Houston's ex, Bobby Brown. The new season starts February 14, 2010.
