Since we were already talking about 'The Hills,' here's one more thing. After the series finale, stars Kristin Cavallari and Brody Jenner showed up to speak with the MTV hosts, where they discussed everything that took place on the reality show.

On 'The Hills Live: A Hollywood Ending' (Tue., 11PM ET on MTV), Kristin and Brody talked about the story behind the series. And while dishing out the real dirt, Brody seemed to admit that everything that happened on the show was fake.

Brody referred to the soon-to-be infamous ending of the series, where the camera pulled back and revealed him standing on a stage set, showing him surrounded by television equipment. He wouldn't even admit to whether he had actually had a relationship with Kristin.

Jenner said this: "As you saw in the end -- what's real and what's fake? You don't know. Our relationship the entire time could have been fake. You don't know; you don't know."

"You'll never know!" Kristin added.

Groovy. Thanks, guys. Nothing we like better than reality stars mocking their viewers for actually believing that we were seeing real details about their lives. Well done, 'The Hills'!
