Fergie Not Pregnant—Just Fat!

The Black Eyed Peas singer isn't the first celeb to get plump-alicious for work. See her and many more in our new plus-size stars photo gallery

Whoa! Is that Fergie prancing around in Nine, or is it just her fatter twin sister?

Yup, it is the Black Eyed Peas' leading lady. She purposely packed on about 20 pounds to play a pump-alicious 1920s Italian whore in the just-released movie musical.

Ms. Fergie isn't alone in the girth-for-gelt department. She follows in the method-acting, plus-size footsteps of folks like George Clooney, Matt Damon and Charlize Theron, who have also let themselves go to play characters with bigger waistlines, bellies and bootys.

Check out our new gallery for these and more unforgettable Hollywood fatties, including one hottie who packed on a whopping 67 pounds for his wide-load role.
