After months of rumors that [article id="1616610"]Kevin Federline was working on a reality-TV project[/article], Britney Spears' ex-husband has been confirmed as a participant on the next season of VH1's "Celebrity Fit Club," People reports.

The news was first reported by TMZ, which said he was spotted going onto the set of the show in Simi Valley, California. Calls to both VH1 and Federline's rep to confirm the report were not returned to MTV News.

The former backup dancer, who has been publicly criticized for his recent weight gain, will reportedly star alongside another of his exes: ex-girlfriend and mother of two of his children, actress Shar Jackson. TMZ also reports that other notables for the season include former "Baywatch" star Nicole Eggert and Whitney Houston's ex-husband, Bobby Brown. According to People, the new season of the show will kick off on February 14, 2010.

In July, MTV News reported that Federline was trying to get a reality show about his own life that would include girlfriend Victoria Prince and his two sons with Spears, Jayden James and Sean Preston. Federline was said to proposing the show to VH1, the same place he'll star on "Celebrity Fit Club."

This isn't Federline's first foray into reality TV. After starring alongside Brit in 2005's short-lived reality show "Britney and Kevin: Chaotic," he reportedly had planned to be in another show in 2008 but canceled it due to Spears' public troubles at the time.
