Dance Your Ass Off, Oxygen’s well-rated weight-loss/dance competition series, will bring aboard Top Chef and original Project Runway production company Magical Elves for its second season, airing in 2010. A network rep told EW that Oxygen is planning announcements concerning on-camera talent — including first season host Marissa Jaret Winokur (the original Broadway cast of Hairspray) — at a later date.
