Uh-oh, spaghetti-O. Kanye West's performance at Bonnaroo didn't exactly go according to his all-encompassing plan. The rapper previously played Bonaroo in 2008 and thrashed the stage after he claimed his show was sabotaged by organisers and Pearl Jam, who had played before him.

Nevertheless, Kanye returned to the festival and claimed that the last time he was there, "they had 'fuck Kanye' written on the port-a-potties. This time, we're going to piss on them." Right so.

Kanye then reportedly removed any mention of Jay Z from his lyrics throughout, sparking rumours that he's in a feud with the rapper after he reportedly snubbed his wedding to Kim Kardashian last month.

As the set wore on, Kanye got even more and more angry and repeatedly shouted "Where the press at? Fuck the press!" at the audience, who then roundly booed him. Unphased by said booing, Kanye continued his set.

Here's the video of said booing.

Were they saying Boo or Boo-urns?
