Audrina Patridge and Lauren Conrad are dunzo.

In a September 5 interview with Celebuzz, Patridge, admitted she no longer stays in touch with Conrad, 26, whom she met when they began shooting the MTV reality show The Hills in 2006.

"I don't really talk to Lauren or see her at all," Patridge revealed. "I think there was a little bit of a falling out. We kind of went our separate ways. The show brought us together and without that show, we all kind of go back to our own thing."

The former roommates haven't been photographed together since the Hills series finale party in July 2010.

Though Patridge doesn't speak to Conrad's ex-BFF Heidi Montag, either, she does keep in touch with at least some of her former costars. "I speak with Stephanie [Pratt] every now and then, Kristin [Cavallari], Brody [Jenner] and Justin ["Bobby" Bresica] — I ran into him. That's it."

Despite the distance between them, Patridge would jump at the opportunity to reunite with her former costars on the small screen — someday.

"Give it another year or two years, because then everyone will be established," Patridge said. "I feel like between two years ago and now, everyone is transitioning and figuring it out."

While Conrad's professional career continues to thrive, thanks a successful clothing line and book series, Cavallari, 25, recently welcomed her first son, Camden Jack, with fiance Jay Cutler. Pratt, meanwhile, is currently dating Line Snob app co-founder Julien Chabbott.

Until a proposed reunion happens, Patridge — who starred in her own VH1 reality series in 2011 — is busy building a life with her boyfriend, professional BMX rider Corey Bohan, 30. "I'm 27 right now," Patridge told Celebuzz, "so I want to be married before I'm 30."
