Us Weekly reports that Jillian Michaels wants to quit Biggest Loser because she is tired of being the "bad guy."

A source tells Us Weekly that Michaels regrets returning to the show after her departure in 2011.

"They paint her to be an a--hole," the source said. "She's the only woman trainer, and she gets a bad rap,"

Michaels was one of the original trainers when the show began in 2004. She left in 2011 to focus on being a mother to her two kids, and to do more charity work. Michaels returned to the series in 2013, and just completed the shows 15 season.

However, sources tell E! News that Michaels is leaving because she is unhappy with the results of last season after winner, Rachel Frederickson, lost a shocking amount of weight.

"Nothing is official yet, but Jillian has said she wants off TBL," the source explains. "She wasn't happy with how last season went. The shocking weight loss of Rachel doesn't do the brand any favors and she wants to distance her name from it."

NBC and Michaels' representative, Leslie Sloane, have not commented in regards to her exit from the show.
