Which is why rumours are building that it's all a great big fake. A report yesterday claimed that Joaquin Phoenix is only getting up to all these shenanigans because he and Casey Affleck are pulling a big Andy Kaufman-esque art prank on everyone, and the end result will be a spoof documentary lampooning self-important stars and, we guess, the gullibility of the media.

But that's not the case at all, says Joaquin Phoenix's mouthpiece Susan Patricola. Joaquin is definitely a rapper. Definitely. MTV reports: "The transition from one career to another is never seamless. It should come as no surprise to anyone that Joaquin came from a musical family, in addition to winning a Golden Globe for his portrayal of Johnny Cash. He intends on exploring his musical interests despite speculative, negative or positive reactions." - more on this story
