X Factor brothers John and Edward Grimes reportedly rowed backstage after their Saturday night performance.

Neither Simon Cowell nor Dannii Minogue appreciated the boys rendition of Ricky Martin’s ‘She Bangs’ and when the boys got backstage they began to blame each other for the fiasco.

A source told The Mirror: “Edward was blaming John, who had a go back before they spent some time apart. It was all smiles for the cameras but they were arguing for ages.

“Everyone knows they are not the best singers, but they don’t want to just get sympathy votes or go through because of the stage show Louis Walsh is organising around them.”
