Kirstie Alley to appear in weight-control ads

"Fat Actress" star Kirstie Alley has signed a deal to appear in ads for the Jenny Craig weight-management program.

Alley, who has said she wants to lose the weight that prompted her new Showtime series, will star in Jenny Craig Inc.'s 2005 advertising campaign. The TV commercials will begin airing Jan. 10, the company, based in Carlsbad, Calif., announced Monday. Terms of the deal weren't disclosed.

"I had a great time getting fat, and now I'm going to have an even greater time losing weight," Alley, 53, said in a statement.

Alley's goal is to lose more than 50 pounds. She lost more than 15 pounds on the program 14 years ago, the company said, and kept it off for over 10 years.
