Former Seinfeld funnyman Jason Alexander is the latest star to step onto the scales for Jenny Craig - he's set to shed weight as the diet firm's latest spokesperson.

The actor, who played tubby George Costanza in the hit sitcom, follows in the footsteps of Valerie Bertinelli, Phylicia Rashad and Kirstie Alley as the firm's new face and body.

He's hoping to lose between 30 and 40 pounds on Jenny Craig's weight-loss plan, which he picked because "I'm fat and they (the programs) work!"
