Actor Joaquin Phoenix dove into a crowd of hecklers during his performance as a rapper on Thursday morning at the Fontainebleau Hotel's club LIV in Miami Beach.
Miami Beach police did not make any arrests. But was it artist's rage or publicity staged?
While on stage Phoenix said "I've got millions of dollars in my f*&** bank account. What do you got?" Then he proceeded to attack the heckler. Dozens of security guards pounced on the scuffle, as party goers jumped out of the way, witnesses told Crime Scene.
One of the event's hosts Alexis Mincolla said he thinks it may have been an act.
"The film crew he had with him seems like an act to me," said Mincolla. "Casey Affleck is working on a documentary" about Phoenix's career shift.
Affleck is Ben Affleck's brother and Phoenix's brother-in-law.
Witnesses at LIV on Thursday morning may have criticized Phoenix's rapping skills, but his acting skills are still superb.
This is not the first time Phoenix abruptly leaves the stage. Watch him fall off stage during a performance at a club in Las Vegas on January.
You may be able to catch more Phoenix drama tonight -- He and Demi Moore are set to attend an after party for the Miami International Film Festival at Bella Rose, 423 16th St., in South Beach.
