"I miss her personality – because she is not the same person anymore," Conrad said Wednesday on Ryan Seacrest's KIIS-FM radio show. "I was best friends with her for two years and now I feel like I don't even know the same person anymore."
The fight originated after rumors spread that Conrad had made a sex tape with her ex-boyfriend, Jason Wahler – rumors which she believes Montag, 20, and her fiancé Spencer Pratt started. Conrad, 21, denies she ever made such a tape.
And their famous fights on TV are real, she says. "I wouldn't fight for the camera," she said. "If anything I would try not to."
Asked if she thinks the duo will pull a Paris and Nicole and eventually make up, Conrad answered: "I mean I don't think so, you never know though. Probably not. I can see us getting to not hating each other but I don't think we would ever go back to being best friends."
