But her mother isn't going down so easy.
In an obscenity-laced rant caught on camera Wednesday night outside Hollywood hotspot Beso, Lynn Patridge swore her daughter was meant for bigger things and took aim at her daughter's former The Hills castmates.
"Audrina is going to f––ing rise. And She's got class ... She's a Polish, Catholic, f––ing full-on Italian," Lynn, smoking a cigarette, said into the camera. "Not only that, she was raised right."
During the five-minute diatribe, a friend attempted to intervene to stop the interview but Patridge, who admitted she'd been drinking, resisted.
"I've been a celebrity mom for eight years through this Hills" bull–," she said, "but Audrina is going to the next level... She's got it in her. She's a sweetie."
Lynn also addressed Audrina's surprise DWTS elimination. "One door closes, another one opens. I was proud of her," she says. "Last night, she f––g kicked a– . . . It's all show business, baby, the show must go on."
And she picked her favorite to win the ballroom competition now that her daughter is out: "I hope Brandy wins, Brandy and Maks."
But she wasn't so nice when asked about the "Hills girls" – her daughter's costars in the MTV reality show. She called them "Hills tramps" and targeted Lauren Conrad in particular, calling her a "b––."
A rep for Audrina did not immediately respond to a request for comment.
