This is no beef with Rihanna. Looks like Joan Rivers , and her fashion guest went harder on Rihanna then Ciara did. All Ciara said was that when meeting her she wasnt all that pleasant. Joan is the one that actually called her a BITCH ! Lol so actually the beef should be with the old white lady. Media stop playin into all that bullshit. Reading more into certain things ,and making up stories where there is none. Joan is looking for some ratings for that show thats all.
