Singer Katy Perry turned down the chance to join The X Factor judges panel because she says she is not ready for it and it is too early in her career to be judging other singers.
The 27-year-old says she felt uncomfortable giving her verdict on wannabe singers.
"There's not actual paper contracts, but people have been interested in me judging other people. I would do it but I'm just not ready for it yet. Maybe in the future, I would love to," dailystar.uk.co quoted Perry as saying.
