According to the Daily Star Kid Rock's last minute Download cancellation was due to a lack of facilities for his band, not illness as organisers had claimed.
The singer who has recently scored a UK number one with 'All Summer Long' was due to perform on the main stage of the Donington festival on the Friday (13 June), but cancelled hours before he was set to take to the stage.
Speaking to the Daily Star Kid Rock said: "They treated me like a fuck. There was just one trailer for my whole band. We had no water, no bathroom, no rider.
"The final straw was when they wouldn't give my crew any food or drinks vouchers.
"I called the promoter and told him he had two hours to get it sorted or I was out. They did nothing so I visited the promoter's office, took a piss on his couch and left."
At the time organisers told fans that Rock, real name Robert Ritchie, had pulled the show because he was ill, but the rapper told the paper: "I was wandering the streets in Birmingham, trying to find a good movie to watch."
He slot was filled by extended sets from Judas Priest and Disturbed.
