Joaquin Phoenix had everyone scratching their heads after throwing an apparent fit before an appearance in Vegas Friday night. According to Page 6, the newly-minted rapper was getting ready for soundcheck but got pissed when his personal documentarian Casey Affleck and his camera crew didn't show up on time. "Thanks for being late and fucking everything up," Joaquin reportedly exclaimed before storming out. Then, per an eyewitness, "He came back five minutes later and did the soundcheck. Nobody can tell if he is for real or if this is all a big joke." I still say joke. But it's possible Joaquin has really just lost his mind.
