Pop singer Robbie Williams is reportedly so obsessed with 'X Factor' that the producers have to send tapes of the show to him.

'X Factor' presenter Kate Thornton reportedly told Heat magazine: "Rob is as obsessed with the show as the rest of the country."

She also said that tapes of each show are now sent to the singer, who is currently based in LA. "I think Robbie thinks that Shayne has a good chance of winning," Thornton said in the interview.

Seven contestants now remain to battle it out in 'X Factor' over the coming weeks.
