0703_hills-launchWe'll never tire of behind-the-scenes tales from "The Hills."

Brody Jenner has been spilling a ton of personal information on his new podcast, "The Brody Jenner Podcast with Dr. Mike Dow," and this time he's opening up about who he has and hasn't hooked up with in Hollywood.

In his latest segment, Dow started to name off some of Brody's exes, but when Lauren Conrad's name came up, Jenner denied that the two ever dated for real.

"Lauren and I have always been just friends," the 30-year-old explained. "We worked together on a show called 'The Hills' where we had to pretend like we were dating but we never dated."

But the "Keeping Up with the Kardashians" star says he did in fact date fellow costar Kristin Cavallari ... but not while they were filming the MTV reality series.

"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," he revealed.

It's interesting that Brody says he never dated Lauren, though, since Conrad opened up about their on-screen love affair to Allure in 2012 -- and told a different tale.

"Brody and I did date," she said at the time. "It was pretty brief. There was definitely editing to drag it out."

So, did they or didn't they? You decide!
