(Cover) - EN Showbiz - Kirstie Alley has lost 100lbs in weight, she has revealed.

The 60-year-old actress started her weight loss journey just prior to appearing on Dancing With The stars but the energetic show certainly helped her slim down.

The former Cheers star has battled with her weight over the years and is an infamous yo-yo dieter.

But Kirstie says she feels better than ever and is proud of what she has achieved.

"I've lost 100 pounds," she told Entertainment Tonight. "I feel like I'm back in my element. I honestly didn't even realise what I looked like."

Kirstie appeared on the catwalk for the Zang Toi runway show during New York Fashion Week last night and said that she is now wearing the smaller version of his designs.

"Before Dancing With The Stars, I bought these dresses from size 14 to 4," she shared.

"[They were] all the same dress, and I said, You know what I really want? I really wanna be in this dress in a 4!"

Although Kirstie is happy with her transformation, she says she will not be adding to her new look by going under the knife.

"I haven't had plastic but here's the reason; People do plastic surgery to make you look younger," she said.

"I don't think it makes you look younger. I think it can make you look weirder."

The frisky actress is also looking to spend more time with the opposite sex but says she does not want anything too serious.

"This is what I think about sex," she said unreservedly. "I think it's fun to hook up every night for six months Then it's time to move on!" (C) Cover Media
