Boyzone star Ronan Keating has revealed that only John or Edward Grimes can actually sing.

The brothers will appear on tonight’s X Factor show, where Ronan will comment on their lack of chemistry, causing them to break down in tears. Making matters worse, today he told The Sun:

“There’s something about those guys – they’ve got the right energy and feel really pop.

“And one of them can sing – I don’t know which one but one of them can.”

That’s a backhanded compliment if ever I heard one!
