UPDATE: Several sources are now claiming that Phoenix’s new rapping career is an elaborate hoax.

Who’s that guy Diddy’s staring at? Believe it or not, that’s Walk the Line‘s Joaquin Phoenix. The two - along with Casey Affleck -  were spotted partying in Miami Beach earlier this week.

Just a few months back, the Oscar nominee announced that he was giving up acting to focus on his musical career. Hopefully, he’ll also find time to focus on showers and shaving during his retirement. (You can see more pics of the 34-year-old’s new look after the jump.)

Phoenix still has one more film set for the big screen. Two Lovers, also starring Gwyneth Paltrow, is scheduled for a February 13 release.
