So we now know what Heidi Montag does when she’s not in front of the paparazzi or getting plastic surgery, she works out.

At her heaviest, the 5’2″ fame whore claims she weighed 130 pounds, but she is now down to 103 pounds.

How did Heidi lose 27 pounds so quickly without more lipo?

“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,” Montag told Us Weekly. “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.”

“I’ve been running a lot, and I’ve been doing weights,” she adds.

Heidi recently just hosted the Wet Republic party in Las Vegas. The same party runaway bride, Crystal Harris, was spotted partying at the day she was to be married to Playboy Hugh Hefner.

I actually believe that she works out 14 hours a day.

I mean, what else is she doing?
