Kevin Federline Wants to Get "Fit"

Former back-up dancer Kevin Federline is set to join the newest season of "Celebrity Fit Club." The interesting part is that ex-girlfriend and mother of two of his kids Shar Jackson will also be part of the cast.

Federline has gained weight in the three years he has been apart from ex-wife Britney Spears. It is ironic since Spears packed on pounds during the marriage and Federline retained his physique, where as now the tables have turned. Spears has recently gotten back into shape.

It has been rumored that Kevin Federline was supposed to be starring in his own reality show.

Joining Federline in the quest to slim down will be Bobby Brown, and the former "Baywatch" babe, Nicole Eggert.

He has recently been spotted in Simi Valley, California visiting the set of the show on Tuesday.

VH1 will premiere its seventh season of "Celebrity Fit Club" on February 14, 2010.
