It turns out there was nothing real about that part of the former MTV reality show.
"Lauren and I have always been just friends," he continued. "We worked together on a show called The Hills where we had to pretend like we were dating but we never dated."
The 30-year-old reality star did have a relationship with Cavallari though, 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."
Now, Jenner is dating model Kaitlyn Carter, who he's been showing off on his Instagram page, posting pics of her in teeny bikinis during their romantic vacations and coupled up shots with her in various other places.
He isn't the first former Hills star to come clean about the show's scripted past, though. Cavallari and Audrina Patridge both said they made things up for the show, with Cavallari saying on Bethenny last year, "I faked relationships, I faked fights." Meanwhile, Patridge told Celebuzz earlier this year some of the scenes were "manipulated" and "verbally scripted."
