With shooting of the fourth season of The Hills
about to wrap in a few weeks, Audrina Patridge
, 23, is addressing speculation about the show's future.
"There is going to be a fifth season," Patridge tells PEOPLE. "We just found out."
Patridge, who recently filmed the thriller Sorority Row
with Rumer Willis
, adds that -- despite all the drama -- she and her costars have a good time filming the show: "We have fun with each other and we've stuck it out this long, so we might as well do another one."
But Patridge admits that the cast's divergent interests have made filming difficult.
"At one point, all of us were like, 'No, we don't want to do another season,'" she says. "I wanted to do more movies, and Whitney
moved to New York and she's doing her own spin-off
. And Lauren
's dating My Boys
actor Kyle Howard
but he can't be on the show because he's on another show, so that makes it hard."
Something else that wasn't easy: Recent buzz that Conrad had a fling
with Patridge's sometime-boyfriend Justin Bobby
"It was really hard -- one of his best friends that told me that, and I called Lauren and she hangs up on me," Patridge says of the rumor, which turned out to be false. "And then once I sat them down and talked to them, I was like, 'Okay, this is all I needed!' You'll see it on the show. It was very emotional." -- Beth PerryTell us: Will you watch another season of The Hills?
