Chanel Iman loves her fuller figure!

The Victoria's Secret siren is carrying an extra 13 pounds on her 5-foot-9 frame.

"I eat to gain," she told UsMagazine.com while promoting The Incredible by Victoria's Secret bra in NYC Tuesday. "I'm a big believer in having hips, butt and thighs!"

How does she do it? "I'm eating everything from steak to mashed potatoes; people hate me!" Iman, 20, laughed.

As decadent as her diet sounds, keeping the pounds on is no easy feat for the model. "It's very difficult for me because I'm naturally skinny," she said. "I have to put on a lot of weight and work out to gain muscle. I love curves and being sexy."
