Kim Kardashian has revealed that she maintains her ample rear with a diet of junk food.

The sex-tape turned reality TV star confesses in a new interview that she’s failed miserably in her attempt to stick by her New Year’s resolution to eat healthily in 2008.

“I figured just eating well would help me lose five pounds or so,” Kim told People.

“It’s so hard to eat well because I love so many unhealthy foods. I just can’t stop eating junk. It’s awful!”

Kim is apparently relying on exercise to burn off those carb calories.

“I’ve got a personal trainer who keeps me active,” she says. “I work my butt and legs just about every day, and I do cardio to burn fat. I’ve actually started videotaping my workouts so I can do them on the road.

“I’m going to start selling the videos soon on my Web site so that others can do the same workout that I do. They’re short videos, but if you do them one right after the other, it’s a really good workout.”

Would you do Kim’s work out?
