Reunited exes Ryan Cabrera and Audrina Patridge are dunzo once more.

Cabrera, 27, rekindled a previously-failed relationship with Patridge in January, and was spotted filming scenes for the soon-to-be axed Hills in Los Angeles — but it’s all over now and Audrina has been popping up at parties all over Hollywood stag.

“Ryan and Audrina are definitely not together right now,” a motormouth muttered to E!’s Marc Malkin this weekend. “It’s still a touchy subject for her…Audrina’s not talking about it, but people were talking about it over the weekend.”

Another source said: “Audrina came to Perez’s [Blogger Perez Hilton] birthday with a girlfriend. When she was asked, ‘Where’s Ryan?’ she made a mortified face and changed the subject right away. She gave off a weird vibe and seemed very awkward.”

The couple’s romance was filmed for the upcoming sixth and final season of The Hills, but there is no word if the breakup will be featured.

Word is the split between the musician and the busty brunette may have something to do with Ryan’s alleged obsession with another ex-girlfriend, Riley Keough, who just happens to be Elvis’ granddaughter.

In February, Star Magazine claimed Ryan hadn’t given up hope of convincing Riley, who moved in with the much older star when she was just 17, to give their love another chance. He had reportedly been texting and calling the beauty incessantly behind Audrina’s back.

“Ryan believes he has a spiritual connection with Riley,” a snitch said at the time. “He really misses her and wants her back.”
