Kirstie Alley is shrinking before our eyes!
The gorgeous Dancing With the Stars alum stepped out in a bright purple dress that perfectly accented her newly-svelte frame, as she made her way into the David Letterman Show on Monday.
Before heading out the door, Alley hurriedly Tweeted: "Madly scrambling to get ready to confront my estranged lover..David Lettermanâ€¦I shoot it tonight. It airs Thursday. I gotta zip outta NYC."
Since finishing at an impressive second place in the DWTS competition this year, Alley has kept up her rigorous workout routine, and it's definitely paying off!
A far cry from the Fat Actress, circa 1998!
Find out what Alley Tweeted when she left the David Letterman Show last night, after the jump ...
