Holly Madison: Melissa Rycroft Is My Biggest Threat on DWTS

"I think the biggest competition is Melissa from The Bachelor," she told Usmagazine.com Saturday at a bash at Prive Las Vegas. "She is an amazing dancer and everybody loves her, including me."

The first day of filming, they hid in a dressing room together because "we were supposed to be secret, surprises guests" after Nancy O'Dell and Jewel dropped out due to injuries, she said.

"I got to know her a little bit," Madison told Us of Rycroft. "She is super sweet and an amazing dancer."

She said she doesn't think "it's unfair" that Rycroft, a former ballet dancer, has a dancing background.

Said Madison, "I wish I had that advantage."

"I'm not a dancer at all," she went on. "Every week it's a completely different style. Today I was such a brat at the dance studio. I was kicking the walls! I mean, it's six hours a day straight! This guy [partner Dmitry Chaplin] does not give me a break. It's the hardest physical work I've ever done in my life!"

Is she worried she'll be the next to suffer an injury?

"No. I'm thinking really positive," she said. "We've been doing some crazy flips and tricks this week. My side is, like, killing me. I'm going to be a trooper, and I'm going to get through it."

She said she doesn't care if she wins, either.

"I just want to make it to third or second [place]," Madison told Us. "I want to do as many dances as I can and wear as many awesome costumes as I can. I'm having so much fun with it. I want to stick with it as long as possible."
