Television personality Brody Jenner recently admitted his romance with co-star Lauren Conrad on the former MTV reality-TV show “The Hills” was contrived.

During “The Brody Jenner Podcast with Dr. Mike Dow,” the stepbrother of reality-TV star Kim Kardashian, reportedly opened up, saying he has always been “just friends" with the 28-year-old fashion designer. The 30-year-old star was asked by Dow about his purported past relationships, which included those with Kristin Cavallari, Avril Lavigne and Nicole Richie, as well as Conrad.

“That's false. Lauren Conrad and I never dated,” Jenner reportedly said, adding: “Lauren and I have always been just friends. ... We worked together on a show called ‘The Hills’ where we had to pretend like we were dating, but we never dated.”

Jenner reportedly admitted to his relationship with Cavallari, saying: “I dated Kristin when we were very young, when she was on ‘Laguna Beach’ and I was on a show called ‘Princes of Malibu’ with Spencer Pratt ... we met at a party in Hollywood ... but during [‘The Hills’] when we filmed, Kristin and I did not date, we were not hooking up.” The reality-TV show aired on MTV from May 2006 to July 2010.

Jenner is currently dating model Kaitlyn Carter, and the two have been open about their relationship. Carter has posted photographs on Instagram of herself with Jenner during their romantic vacations.
