Kelly Bensimon and Bethenny Frankel, Real Housewives of New York
When Bensimon joined the cast of the Bravo hit, she and the 38-year-old chef did not get along. After Frankel criticized Bensimon -- who was arrested in March for assaulting her ex-boyfriend -- for refusing to help with a charity event, Bensimon told Frankel she was above her because "I won't put up with your antics and bulls--t... While you're busy talking, I'm busy doing things. I don't like you."
