Hollywood's Best Celebrity Feuds

In matters of Lauren vs Heidi, it truly was a case of bros before hos.

From College Candy: "Former BFF's Heidi Montag and Lauren Conrad are still not completely back to normal after Heidi picked now-husband Spencer Pratt over Lauren continously during Season 2 of The Hills. Not only that but Heidi and Spencer started a pretty awful sex tape rumor about Lauren that led to some pretty entertaining screaming fights on their show."
