Kirstie Alley: "I've Lost Over 50 Pounds"

It seems as if actress Kirstie Alley is successfully tackling her weight-loss goals.

"I've lost over 50 lbs and I'm having the time of my life," the former "Cheers" star and Jenny Craig spokesperson wrote on her Twitter account.

Alley, who also says she has "30 more [pounds] to go," showed off her new look in front of the paperazzi in Hollywood recently.

In the past, the 59-year-old star has openly publicized her weight- loss struggles. She chronicled her quest to shed a few pounds on her A&E reality show, "The Big Life" and also admitted to Ladies Home Journal in May that she once tipped the scale at 230 pounds.

"By 2008, my weight started creeping up and I said, 'Oh, I still look good at 150. I still look good at 155. I still look okay at 165. Some of my clothes still fit at 175,'" she told the magazine. "And nobody was saying 'You're fat.' I was like a bank robber who was getting away with it."

Now, with the help of her new weight-loss system, "Organic Liason," Alley is successfully losing the weight while also regaining a new sense of self-esteem.

"Back from Italy, found the love of my life....turned out it was me," she tweeted.
