'Hills' Star Kristin Cavallari Had To Warn Dad About Her Girl Kiss

'I had to call my dad and say, 'Dad, sorry — this is going to be your least favorite episode,' ' star says.

NEW YORK — Kristin Cavallari came back to reality TV with a bang. In her first few seconds back on MTV in her [url id="http://www.mtv.com/shows/the_hills/season_5/series.jhtml"]"Hills"[/url] debut, the former "Laguna Beach" star almost immediately got into a cat fight. As the season progressed, she put the moves on two of the show's leading men, Brody Jenner and Justin Bobby, resulting in spats with both Jenner's girlfriend Jayde Nicole and Justin's ex Audrina Patridge.

"Gosh, top moment ... I think I had a couple," Cavallari told MTV News at "The Hills" finale on Tuesday (December1). "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.' "

But Cavallari doesn't seem to regret any of those romantic entanglements. Instead, it's her now-infamous girl kiss that she kind of wished didn't happen. "I think that sort of my I-wish-I-didn't moment was when I made out with Stacie in Vegas," she explained. "That was one episode I had to call my dad and say, 'Dad, sorry — this is going to be your least favorite episode.' "

It was a moment that not only surprised the audience at home, but also her father. "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," she laughed.
