Following in the step of Lauren Conrad, Audrina Patridge just announced that the upcoming season of The Hills (premieres on September 29 at 10 pm), will be her last!

"I'm almost done with The Hills. We're in the middle of finishing these episodes, and I'll be leaving then," Audrina says. "It feels like I'm graduating. I'm taking the next step and growing up and maturing and moving on in my life."

But Audrina's not leaving the spotlight entirely -- she's turning to her true passion, acting! "I moved to Los Angeles to be an actress, and before I got onto The Hills," she reveals. Her next project? The new horror flick Sorority Row, with Rumer Willis and Princess Protection Program's Jamie Chung, that comes out on September 11.

Are you sad that Audrina is leaving the show? Will you still watch after she's gone?
