Biggest Reality Show Catfights
Gretchen Rossi and Tamra Barney, Real Housewives of Orange County
Barney accused Rossi of cheating on her late fiance Jeff -- he recently died of cancer -- and that they had a "relationship of convenience" in which Rossi dated a man named Jay. During a reunion show, she denied Barney's story and said Jay was just an ex. Rossi -- who also did some heavy flirting with Barney's son -- added, "Do you really hate me that much that you need to say the most ludicrous thing I've ever heard?"
