What's Beef: T-Pain Vs Jay-z

So it being said that T-Pain has beef with Jay-Z even the random unplanned on stage performance of D.O.A. (Death Of Autotune).

T-Pain was recently caught on video sayin "Fuck Jay-Z, he is 59 years old. I don't think he has the right to say what's good and what's not, I think if anything is dead, it should be him. ... To any Jay-Z fans out in the crowd, excuse the fuck outta me. But you don't see me saying 'rap is dead,' even though it is. 'Cause apparently all the rappers are trying to do T-Pain."


Now the thing thats crazy to me is that he was seen on stage with him while performing and was interviewed praising Hov for the song sayin' "D.O.A. is the best song I've heard in a couple years," T-Pain said on his Twitter page. "Watch me get back out here and do my thang." The rest is here

So I think this is a really bad idea, I mean there have been rumors that T-Pain was just joking and all, but if he wasn't this could mean real trouble...
