Kirstie Alley's winning the battle of the bulge!

The "Dancing With the Stars" runner-up has majorly slimmed down since her stint on the ABC show. "I've lost 100 pounds," she told Entertainment Tonight in an interview that aired Tuesday.

"I feel like I'm back in my element," the 60-year-old said. "I honestly didn't even realize what I looked like."

On Tuesday, Alley strutted her banging body on the Zang Toi catwalk in NYC. Clad in an elegant-yet-dramatic royal blue, rhinestone-adorned gown, she wowed the audience as she closed her designer pal's Spring 2012 show.

"Before "Dancing With the Stars," I bought these dresses from size 14 to 4," she explained. "[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!'" 

So does the actress — who says she is indeed now a size 4! — want to follow up her weight loss with a little nip and tuck? "I haven't had plastic surgery 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 like it can make you look weirder."

Alley's trim new physique might attract some more male suitors, but they should be prepared: she's not looking for anything long term! "This is what I think about sex," she said bluntly. "I think it's fun to hookup every night for six months ... Then it's time to move on!"
