Here's a video clip of Kirstie Alley wearing her bikini on the Oprah show yesterday. (Update: The original video is no longer available, what you see above is David Letterman's take on it). Kirstie used to weigh about 220 pounds but she's lost a lot of weight since becoming a spokesperson for the Jenny Craig weight loss program almost two years ago.

Update March 2008: Oprah Winfrey's Harpo Prods. has signed a development deal with Kirstie Alley for TV projects. It's unclear whether the deal might include a syndicated daytime talk show or a program for Winfrey's new cable channel.
