Rihanna and Katy Perry don't talk to each other because of their boyfriends

Katy Perry never liked that Chris Brown and Rihanna are back together, and this has weakened the friendship between both girls. But now RiRi has started to critise John Mayer.

These are the literal words of a witness for Star Magazine : "Rihanna says that Katy is a hypocrit because she is going out with John Mayer, who is a womanizer and the worst person all over the world". It is right that Katy's boyfriend is known for being a playboy, but if you compare him with the guy who hit Rihanna maybe he is not that bad.
