Oscar/Grammy winner Jennifer Hudson is the latest celeb sporting a milk mustache for the popular Got Milk? nutritional campaign. The slimmed-down superstar and new mom credits the white stuff, combined with a lifestyle of exercise and healthy eating, with helping her lose 56 pounds to play Winnie Mandela in the forthcoming biopic Winnie.

“A lot has changed since I first hit the stage,” the new mom says in the ad. “Now I’m a news mom with an audience of one. And who’s the star of my show? Milk. It’s the elixir that builds strong families. Talk about a powerful performance.”
