Kirstie Alley has debuted a new body (again): The actress says she's dropped 50 pounds!

Alley revealed her weight loss on Monday's Today, telling Matt Lauer that she kept her promise that she'd dropped the weight by the new year. Back in April, Alley, who's a paid spokesperson for Jenny Craig, said she planned to drop 30 pounds. Although she said she has an easy time losing weight, she struggles with keeping it off, but "this time it's different."

"My goal is to keep this and maintain this throughout my life," the actress explained. "I feel like I've conquered that now. I'm sort of hardheaded. You know, when I used to do drugs, it took me a while to quit, quit, quit — and then it was done. And I feel like that's occurred for me [with my weight now]."

Alley, who turns 64 next Monday, has been open about her weight struggles. Back in 2006, the Cheers alum walked on to the Oprah show in a bikini, showing off her 75-pound weight loss, but then put some of the weight back on before her first stint on Dancing with the Stars in 2011.
