X Factor twins John and Edward Grimes are already aware of the fact that they can’t sing, it hasn’t put them off trying though.

Now magazine has reported that the cocky twins are decidedly less confident in their abilities than they may seem.

A source told the magazine: “It’s all bravado. They are deeply insecure and actually can’t sing that well.

“They’ve even asked other contestants for mini crash-course lessons in harmonising and how to hit the right notes. They can’t believe they’ve got this far.”

Seems like the crash course didn’t work so well, if last night’s performances were anything to go by!
