Audrina Patridge and Heidi Montag aren't as tight as they used to be.

"When we first met, she was really cool," Patridge, 24, said of Montag, 23, on Lopez Tonight Tuesday. "We remained cool. I mean, she's changed a bit."

Her personality has changed, Patridge said, and so have her looks.

"She got her chin chiseled, her nose done again, her cheeks, boobs redone, lipo, butt job, I don't know ten procedures ... in one day..."

She then added, "It's a lot."

Patridge also put an end to split rumors, insisting she and Ryan Cabrera are still an item.

"We have been together. We're not broken up," she said, echoing's original weekend report. "We started reading all of these rumors and seeing it on TV that we broke up. We're sitting there, and we just start laughing about it, like, Wow did we really break up? That's not true."
