She is a poor man's Alexandra Burke who in turn is a Poor man's Leona.
Nothing new here - move on.
Cher = Not the best, but she's different.
Matt = Really needs his own band who can write their own music - if that doesn't happen, just another good singer ala Shane.
One Direction = Can't stand boy bands generally, but these guys are good.
Personally i liked that wacky Katey bird - lovely tone to her voice and was a little off the wall.
Just as an aside - they could make this programme half the length if they cut all the ****e out................
