The Hills star Kristin Cavallari doesn't understand why anyone would claim she abuses drugs, and dismiss the accusations as "crazy."

In the first episode of The Hills this season, co-stars Audrina Patridge, Stephanie Pratt and Lo Bosworth tell Cavallari they're worried about her excessive partying.

'DRUG ACCUSATIONS ARE OUT OF LEFT FIELD'

Cavallari, 23, is shocked by the confrontation. "I went out in Miami and for Super Bowl [in February] and had a good time," Cavallari told E! "I'm allowed to do that."

She adds: "The fact that these girls accuse me of doing drugs...is so out of left field. I mean, I think I started laughing…For them to even accuse me of that is so crazy, but it is what it is."

'I LOST WEIGHT DUE TO STRESS'

The 5'2" Kristin, who lost some 15 pounds last year (shrinking to an estimated 100 pounds) has also been the subject of drug talk because of her dramatic weight loss, which she attributes to stress.

"I've been a little stressed out," she says. "It's terrible, but stress can make you lose weight."

Meanwhile, the single Cavallari insists she's unattached. "I'm not dating anyone!" she says. "It's hard to meet people in L.A. And if I get serious with someone, I don't want to put them on the show."

DWTS HAS APPROACHED HER

Kristin, whose claim to fame is her stint on two MTV reality shows (Laguna Beach, The Hills), reveals she has been approached several times to compete on Dancing With the Stars.

While the exposure on the hit ABC dance competition has helped revive many a C-list celeb's career (e.g. - Mario Lopez, Marie Osmond), Cavallari isn't interested.

"I don't think I could do it," she says. I have a serious fear of public speaking, let along dancing in front of all those people. I think I'd be a nervous wreck."
