Jennifer Hudson is Weight Watchers’ new celeb spokeswoman, the company announced Thursday morning. Ads featuring the Oscar and Grammy winner, 28, begin airing this Sunday.

Hudson and fiance David Otunga welcomed their son David Jr. last August. Now, she's even thinner than before she was pregnant, the new issue of Us Weekly reports.

"Her middle, thighs and butt are more toned than ever," pro Harley Pasternak, who leads her through 55-minute, lunge-filled workouts five days a week, tells Us. "She's excited about her new body," Pasternak adds.

Jenny McCarthy, Queen Latifah and Sarah Ferguson have also served as Weight Watchers spokespeople
