If you thought TV talent contests had trouble with their judges in the UK, it's nothing compared to the diva-off that's rumoured to be going down Stateside.

'American Idol' has reportedly tried to replace Mariah Carey with Jennifer Lopez.

According to The Hollywood Reporter, the US singing competition show was looking to drop the new coach for an old one in an effort to boost ratings.

Carey has been criticised for not actually judging the contestants, even admitting on air that producers talked to her about it.

"This is just another ridiculous 'Idol' judge rumour, likely started by talks of Jennifer performing on the finale," a Fox spokesperson told The Huffington Post in an email statement.
