The celebrity edition of The Biggest Loser is going to be a lot more fun to watch now that soap opera super star Alison Sweeney has agreed to host. The sassy actor plays the notoriously evil Sami on Days of Our Lives and will continue with her role on the show while she tapes episodes of the reality show this spring.

The Biggest Loser challenges participants to lose weight through supervised dieting and exercise. The participant who loses the most weight by the end of the challenge wins $250,000. In the celebrity edition, overweight actors and musicians face off to knock off as many excess pounds as possible.

Sweeney herself has struggled with her weight throughout her life and acting career. She documented her battled to lose weight in her bestselling book All the Days of My Life (So Far), which was released in 2004.
