heels purse Kirstie Alley weight off shoulder hotel

Who's that lady?

We haven't seen Kirstie Alley look this thin and fabulous since her days on Cheers. The Dancing With The Stars finalist has slimmed down so rapidly; we can hardly believe our eyes!

Alley looked beyond thrilled to have ditched those horrid muumuus she used to wear for some sexy, figure hugging outfits and sky high Christian Louboutin heels.

The former Fat Actress was on her way into her hotel in NYC, no doubt gearing up for a hot night on the town.

Work it girl!
