Kristin Cavallari dished about her life on MTV reality show "The Hills" during an interview with Bethenny Frankel on Friday.
"I faked relationships; faked fights," she said. "I don't care anymore -- I can tell you. At this point, it's been so many years."
Cavallari began her reality TV career in 2004 on "Laguna Beach," a reality TV show following a group of high school students from Orange County. In 2009, she took a supporting role on "The Hills."
Cavallari was best known as the show's token party girl and dated several cast members.
"I dated Brody (Jenner) when I was 18, right after 'Laguna Beach,' actually, and that's it," she said.
"And then on the show, 'The Hills,' they had us 'dating' for a few episodes. They pretended that him and Jayde (Nicole) 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."
Now unofficially retired from reality TV, Cavallari and her NFL quarterback husband, Jay Cutler, spend time raising their 16-month-old baby, Camden. She is pregnant with her second child.
