As expected, 50 Cent's new diss track 'Piggybank' has touched a nerve with certain rappers. Fat Joe, a prime target in the song, fired back at 50 Cent in an interview last week. "I really don't care what he thinks," Fat Joe told andPOP, "I'm not the battle rap type. I just think he’s gone crazy." It’s assumed that 50 Cent targeted Fat Joe because of his on-and-off relationship with Ja Rule, whose beef with 50 dates back to 2000. Fat Joe recently appeared alongside Ja Rule in his video for the song 'New York.' "Ja Rule has been a friend of mine since before him and 50 got into a problem. I've been working with him, so he targeted me because I'm supporting him," Joe said, "I never look for trouble with him. I’ve never wanted trouble with him." Fat Joe summed things up, saying "Although I'm Ja Rule’s friend, Ja Rule has never told me, 'yo, let’s get 'em together.' I've never been involved with that so it’s really weird that 50 would be coming at me, but I guess the guy feels he needs this type of hype whenever he comes out with his album or whatever and how more credible could you be then disrespecting Fat Joe?"
