Kirstie Alley won’t be calling Jenny anytime soon.

The former "Cheers" actress is stepping down as Jenny Craig spokesmodel after three years with the company, People magazine reported on Friday.

Alley lost 75 pounds and kept that weight off for more than a year during her stint with Jenny Craig, Scott Parker, vice president of marketing for the company, told People.

"Although Kirstie will not appear in future advertising endeavors for us, she does remain on Jenny Craig's maintenance program and is confident that our program has helped her incorporate positive lifestyle changes that should last a lifetime," he said.

Actress and singer Queen Latifah has joined Valerie Bertinelli as a celebrity spokeswoman for the company.

An ad on the Jenny Craig Web site featuring Latifah states: "I’m taking the first step toward improving my health with Jenny Craig."
