Just like a few of her co-stars from the show, Kristin Cavallari 'fessed up to making up quite a few things while she starred on The Hills, telling Bethenny Frankel on Bethenny, the relationship struggles and other drama viewers saw her dealing with weren't factual.
"I faked relationships, faked fights," the 26-year-old mom told Bethenny in the interview that aired Friday. "I don't care anymore. I can tell you. At this point, it's been so many years."
She even faked her relationship with ex-boyfriend Brody Jenner on the show.
"Brody Jenner at the time was dating Jayde Nicole," Kristin went on. "I dated Brody when I was 18, right after Laguna Beach, actually, and that's it. And then on the show, on The Hills, they had us 'dating' for a few episodes."
"They pretended that him and Jayde broke up and I was dating Brody, and Jayde and I got into a huge fight because she saw us in a club. It wasn't real at all. They were together the entire time."
In spite of her fake relationships on the show, she has still kept up a real friendship with Heidi Montag.
"I have to say, Heidi is one of the sweetest, nicest girls I think I've ever met," Kristin said. "She has such a good heart, and I really mean that. I think she just got caught up in all the hype, which is easy to do.
"I mean, I get it. When I was 18, I probably got caught up in the hype a little bit, too. But she's still the same person inside. I still talk to Heidi all the time."
Kristin also talked about her second pregnancy while she was on the show, telling Bethenny she and her hubby were going to find out the gender "really soon."
"I'm gonna have my doctor write it on a piece of paper, and we're gonna open it on Christmas together."
