Cheryl Cole has just been appointed as the newest judge on this years X Factor, but it seems like her Girls Aloud bandmates may not be too happy with the move.

‘The other girls are very put out that Cheryl has landed the judging role,’ reveals a source close to Nadine to heat magazine.

‘At the end of the day, all the girls are talented but Nadine has got the best voice and as it’s a singing contest she should be the one for the job.

A friend of Sarah’s added: ‘Sarah and Cheryl both wanted to get into TV, but it seems Cheryl is moving closer to that before her.

‘It’s getting really competitive. Sarah always thought that she’d be the TV girl in the group, not Cheryl.’
