Fail Of The Day: The Hills' Heidi Montag Claims To Exercise 15+ Hours A Day

If there's anything to know about former Hills star Heidi Montag, it's that she has a love for addiction. Plastic surgery, ungodly men, and now extreme excercise.

Before she slipped back into a bikini for Saturday’s party at Las Vegas’ Wet Republic — the last time she was photographed in a two-piece was April 2010 — Heidi Montag spent some serious time in the gym.

“I’ve been working out from, like, 5 a.m. to 7 p.m. for two months now. I’ve been working out really hard because I had this pool party and I was like, I have to be in shape,” Heidi told Us Weekly recently. “And I was actually a lot overweight. It was the most I’ve ever been because I’ve kind of been in hiding eating pie with my husband and puppies, so I needed to get back in shape.”

Out of shape being 130 lbs for 5'2" Heidi who's still working on a music career under the wing of Waka Flocka's mom. The reality show girl is happy to be at 103, listing pie and fried chicken as her bulgy weaknesses.

Who can forget those post-cosmetic shots in 2009 when Heidi went under the knife 10 times. “My breasts, because they’re so big, really needed some time,” she explained. “So I’m just starting to work out again after my surgery. Sometimes I get shooting pains, but I hear that’s normal."
