In the first episode of the Hills' maybe-final season, Audrina Patridge, Stephanie Pratt and Lo Bosworth confronted Kristin Cavallari about too much partying.

We'll have a recap of all that action for you a little later, but for now Kristin tells E! she has no such problem, and that the accusations came out of nowhere.

"I went out in Miami and for Super Bowl and had a good time," Cavallari said.

"I'm allowed to do that. But the fact that these girls accuse me of doing drugs, which, by the way, when they bring it up, it's so out of left field."

She thought they were kidding: "I mean, I think I started laughing ... For them to even accuse me of that kind of thing is so crazy, but it is what it is."

Indeed it is.

Kristin laughs off her friends' concerns.

Kristin Cavallari may be thinking about giving it another romantic go with Brody Jenner if the producers tell her to circumstances are right but right now the show's resident bad girl is absolutely, positively single - for better or worse.

"I'm not dating anyone!" The Hills starlet tells us. "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."

Fair enough, so what about all those reports of her spending time with Paris Hilton and Lauren Conrad's ex-boyfriend, Doug Reinhardt, at Coachella recently?

"I've known Doug since I was 15 years old," Cavallari laughed. "Yeah, I saw him there, but not like that ... I'm not going to live my life off of stupid celebrity gossip ... We've been friends for almost 10 years."

Unneeded tabloid attention aside, Cavallari doesn't regret returning to The Hills: "I've had such a great time and it's been great on so many levels."

In other Cavallari news, she says Dancing With the Stars has come calling.

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

Now, strutting around in a bikini, that's a different ballgame.
