Joaquin Phoenix is Hip Hop

Joaquin ain't playing.. or at least he is playing the game. Joaquin jumped off the stage at his performance at the nightclub at The Miami Fontainebleau Hotel last night and got in an audience members face that was harassing him (is this the trend?, Amy Winehouse, Solange?).

First of all what is up? Is this for real or not? In October his publicist confirmed that he was quitting his acting career and start rapping. I need to hear this.

People that were at the club last night stated Mr. Phoenix began rapping to a beat but nobody could make out the lyrics, then he went on to do his little jump off and everything was being filmed by his brother in law, Casey Affleck(Ben lil bro) who's documenting his career switch. Is this for real?
