Watch her lips closely, she is lipsynching - badly. Great dancer and godawful singer, for anyone who really wants to offend their ears you should dig out her performance of Parachute on Radio 1 Live Lounge, it was truly fucking awful. She got away with it when she sang with Girls Aloud, being in a group covers a multitude of sins, when she does an acoustic set (not one dubious song) well then I might agree she can sing. I expect pigs to fly first ;o)
