Lookin' good girl!

Kirstie Alley proudly showed off her newly slimmed-down figure, as she headed to make an appearance on the Wendy Williams show Friday.

The Fat Actress star has shed a significant amount of weight since her stint on Dancing With the Stars -- even landing a spot in the competition's final three, before losing to Hines Ward this week.

After years of up and down struggles with weight, we're ecstatic to see the star looking slim and happy!
