Fat Actress? Not Kirstie Alley!

All the Dancing with the Stars finalist, 60, can do is rave about her post-ballroom body.

"We're doing our dance tomorrow, and you have to wear the costume you wore [during] the first dance that you did," Alley told PEOPLE backstage after Monday night's show. "We had to take a lot of inches out of that costume, which was fun."



The Organic Liaison weight loss system spokesperson even makes shedding pounds sound like a cinch.

"I wasn't so hungry when I was dancing," she says. "That coupled with insane amounts of dancing, I'm sure I lost it faster ... I had the energy the whole way through it and that was sort of astonishing."

And naturally, Alley can't wait to renovate her wardrobe. It feels great to "buy new clothes and look good in them and get rid of all your old stuff," she adds.
