Kirstie Alley hopes to shed 30 pounds on "Dancing with the Stars"

(CBS) - For actress Kiristie Alley, winning the coveted mirror ball trophy is only one of the benefits of appearing on "Dancing with the Stars."

The 59-year-old says she is hoping her upcoming appearance on season 12 of the ABC reality series will help her reach her weight loss goal.

"I've lost 60 pounds, and I have 30 or 40 more to go," the former Jenny Craig spokesperson told US magazine. "And I think with this strenuous, rigorous dance schedule, I think it's going to work. It's exciting."

Alley, who is paired up with pro Maksim Chmerkovskiy, will not be the first contestant to have slimmed down while competing on the show.

Kelly Osbourne famously announced that she lost 42 pounds after competing in season nine. The grueling dance rehearsals also helped season two contestant Tia Carrere to shed a few pounds. And most recently, Disney star Kyle Massey, who made it to the finals with Lacey Schwimmer, said he lost about 30 pounds during season 11.
