Federline, a former back-up dancer, has been spotted looking less than trim in recent months.

The move may come as a surprise as many suspected the father of Britney's two children – Sean Preston and Jayden James – was rumored to be doing his own reality show. He has remained coy thus far about that prospect.

Making his move to the show even more interesting is that his ex, Shar Jackson, is rumored to be a fellow contestant this season, along with Bobby Brown and former "Baywatch" babe Nicole Eggert, according to TMZ.

"Celebrity Fit Club" is entering its seventh season on the network.

Previous stars who have slimmed down on the show included Danie Baldwin, Kim Coles, Gary Busey, Kelly LeBrock, Tina Yothers, Warren G., Dustin Diamond and Chastity Bono.
