Actor turned hip hop artist Joaquin Phoenix continues to act like a freak! Phoenix jumped off stage to take on a “fan” at his hip-hop show in Miami. See the video of Joaquin confronting the heckler below.

Joaquin Phoenix, 34, got on stage around 1:50 a.m. at the Fontainebleau Miami Beach hotel’s nightclub, LIV.

Near the end of his first song, Phoenix walked to the edge of the right side of the stage and called out an audience member whom he thought was heckling him.

“Bitch,” Phoenix yelled. “This is a $3,000 f—–g suit!”

Joaquin then jumped into the crowd as security rushed after him.

It was unclear whether the two men scuffled, but security dragged Phoenix away as the crowd chanted “Joaquin! Joaquin! Joaquin!’”

His brother-in-law, Casey Affleck — who is making a documentary about Phoenix’s career leap from acting to rapping — filmed the entire incident.

Phoenix’s strange behavior, which includes a bizarre Feb. 11 Late Show With David Letterman appearance could just be part of an elaborate hoax.

But Paul Dobransky — a relationships expert and author of The Secret Psychology of How We Fall in Love — recently told the Los Angeles Times that Phoenix could also be schizophrenic, pointing to his “socially inappropriate behavior”

His rep denied the claims: “How absolutely inappropriate for a doctor who has no personal interaction or relationship with someone to diagnose them.”

So is Joaquin Phoenix crazy or is he fooling us all?
