US rapper Kevin Federline is among several celebs looking to shed some weight during a televised stint on Celebrity Fit Club.
The former dancer, who has two children with ex-wife Britney Spears, is joining a celebrity cast on the programme which aims to help stars adapt to a healthier lifestyle.
The 31-year-old's former girlfriend Shar Jackson, with whom he has two children, is also reported to be joining the show.
Kevin, who is currently dating volleyball player Victoria Prince, has hit headlines after piling on the pounds since his split from Britney in 2006.
