Not everything about "The Hills" was scripted.
On last night's "Watch What Happens Live," Kristin Cavallari revealed some behind-the-scenes gossip from the MTV reality show.
Two years after the show went off the air, the 25-year-old star now says the whole thing was "pretty fake," full of "fake relationships" and "fake fights."
And while Kristin says "it was fun because you're acting," there was one aspect of the show that wasn't made up: Her bitter relationship with Lauren Conrad.
When asked if her "distaste" for LC was fake, Kristin emphatically replied "No!"
Check out the video above to see why she thinks the producers were partly to blame ... and find out the three nice things she found to say about her TV enemy.
