Cheryl Cole has reportedly begun her new career as a talent judge on X-Factor by telling contestants to avoid working with fellow judge Louis Walsh.

Filming on the programme began this week after it was announced that Cole would replace Sharon Osbourne on the judging panel.

Although Cole, a member of Girls Aloud, is meant to critique the contestants, she began by turning on Walsh, who used to manage the girl group.

"The contestants said they wanted to have Louis as a boss and Cheryl piped up and joked 'No you don't,'” an insider told the Daily Mirror newspaper.

“With a grin on her face she told them Louis was a rubbish manager - obviously in reference to when he was in charge of Girls Aloud.

“Other than that, the judges have been getting on well. There's lots of smiling and joking and Cheryl was playing her part and being vocal about the acts she liked and disliked."

Cole and Walsh judge contestants alongside Simon Cowell and Dannii Minogue. The programme wil air later this summer.
