Phoenix leaps into crowd at hip-hop show

MIAMI BEACH, Fla. - Joaquin Phoenix appears to be getting into the act of being a petulant hip-hop star.

He jumped off the stage during a short performance at the LIV nightclub early Thursday morning and confronted an audience member who was heckling him. Security guards dragged him back on stage and escorted him away.

It's unknown whether the confrontation - and his pledge to quit acting and start rapping - was real or a put-on, but actor Casey Affleck recorded the performance on camera.
