Demanding trainer Jillian Michaels may have announced on her Twitter page that she’ll be leaving The Biggest Loser after next season, but contestants shouldn’t plan to start slacking or snacking. Two new trainers are slated to join the NBC reality series in season 11, alongside Michaels and Bob Harper, sources close to the show tell EW. (The Hollywood Reporter was the first to report the news.) The twist will be announced on Tuesday’s season 10 finale, although the identity of the trainers will be revealed at a later date. Michaels, who also headlined the low-rated summer series Losing It with Jillian on NBC, departed Biggest Loser once before, sitting out season 3 over business issues before returning for season 4. Her priorities seem to be different this time: “I want to take a year off TV and focus on becoming a mommy and doing more charity work,” she tweeted on Dec. 7. NBC and Reveille Productions, which produces the show, declined to comment. Season 11 debuts Jan. 4.
