Rihanna has apparently dissed good friend Katy Perry as well as fellow musicians Ke$ha and Lady Gaga. The singer was asked about her new album, Loud, and said that it isn't like Perry's "generic pop."

"Every song was tailored to me. I didn't want the generic pop record that Ke$ha or Lady Gaga or Katy Perry would do. I wanted Rihanna songs only I could do."

Well this is kind of shocking considering they were bff's in Las Vegas, should be interested with Katy Perry, and her reaction oh and KEsha too. Yikes Rihanna is not making herself look too good here, I think they should settle it out in a steel cage :).  Heres part of the interview coming straight from Rihanna!
