Take That singer, Mark Owen has said that troubled star Britney Spears was ill advised to appear on this year’s X Factor series.

The star came under a heap of criticism after she obviously mimed her performance and didn’t seem to know where she was or who she was supposed to be watching.

“I think she was ill-advised to appear on The X Factor,” Mark told Heat magazine. “They don’t have the show in the US, do they? I thought it seemed like she wasn’t sure where she was.”

Mark also talked about his own time mentoring the contestants this year and discussed his and Gary Barlow’s ‘good cop, bad cop’ routine.

“I was the good cop!” he said. “I honestly though they were all really good. I had my own favourite, but no, I’m not going to [say] who it was!”
