Get ready for a lot more drama! Lauren Conrad, Whitney Port and Audrina Patridge celebrated the spring season of The Hills at NYC's Gotham Hall on Monday. So what can viewers expect this season?

"Lots of change," the show's creator, Adam Divello, told TV Guide. "It's a lot of things girls in their early twenties go through."

As far as what that means, the cast didn't give away too much. Conrad - who sang along as Mariah Carey performed - did reveal, however, that an old friend becomes a regular. "We move into a new house and my best friend, Lo, becomes our new roommate," she said. Despite being hurt by both Audrina and Brody Jenner, the single Lauren dished that she's patched up her friendships with both pals.

As to whether there's love in the air? We'll have to watch to find out.
