Kirstie Alley revealed her weight loss to Entertainment Tonight in an episode that aired Tuesday.

The 60-year-old actress, known for her widely varying weight throughout her long career, said she is now a size four.

Alley, happy that she met her 100 lbs weight loss goal, then made her modeling debut by strutting down the catwalk in a gown designed by her friend Zang Toi on Tuesday.
