During her years on "The Hills," Audrina Patridge endured some highs and lows with Lauren Conrad (the latter did shed a single mascara tear during an argument), heartache at the hands of bad boy Justin Bobby, some unforgettable nights out at Les Deux, a few exotic trips and a possible fling with Brody Jenner. But after all of the Tinseltown drama, has the host of NBC's travel show "1st Look" been able to remain friends with her former co-stars?

"Once the show ended, we all kind of went our separate ways," Audrina told Joan Rivers during a stop at E!'s "Fashion Police" on Monday. "I needed a break; I was burnt out. And I really needed time to figure out who I was and what I wanted. Cause you have producers telling you who to be friends with, how to act, what to do every day, what to say. And you lose who you are."

So who does Audrina stay in contact with, if anyone? She told Joan that she talks to mom of two Kristin Cavallari and Heidi Montag "every now and then." But don't expect a reunion at Lauren's upcoming nuptials: Audrina recently admitted that she didn't expect an invite.
