Joaquin Phoenix, who retired from acting in October to pursue a music career, made his first appearance as a rapper at a Las Vegas nightclub last week. Sporting long hair and a shaggy beard, Phoenix underwhelmed the crowd with a short performance before falling off the stage. The gig was filmed for a documentary, leading to speculation that the whole thing is a put-on. “This is me saying this is who I am,” said Phoenix. “Are there people out there who think I’m a joke? I’m sure there will be.”
