Kristin Cavallari Regrets Girl On Girl Action: The MTV News Quote Of The Day

"I think that sort of my I-wish-I-didn't moment was when I made out with Stacie in Vegas. That was one episode I had to call my dad and say, 'Dad, sorry — this is going to be your least favorite episode.' He said, 'Great.' He was like, 'Oh, great,' and then when he called me — sometimes he'll call me after every episode just to talk about it — he didn't say one word about the episode. I don't know if that's a good thing or a bad thing ... it's probably a bad thing."

-"The Hills" star Kristin Cavallari, talking to MTV News about her biggest moments on this season of the show, which celebrated its finale on Tuesday (December 1) night. The reality star was referencing a particularly debauched episode of the show, which saw Kristin, Stacie and Justin making their way through strip clubs in Las Vegas. As the night wore on, Stacie ended up wearing a pair of underwear on her head, and by the end of the affair Kristin and Stacie were locking lips. But her return to the show wasn't all negative. "I think my biggest thing was the first episode where I really came in with a bang and it was like, 'All right, clearly I'm back,'" she said. Cavallari first grabbed the spotlight on the MTV reality show "Laguna Beach: The Real Orange County," which followed her and her peers when they were still in high school. Cavallari's return on "The Hills" marked a transition for the show, which had always been centered around Lauren Conrad. But the transition was smooth, and if anything, Cavallari brought the sort of unhinged spark that Conrad didn't have.
