Britney Spears is set to appear on the X Factor cementing her triumphant comeback after years battling psychiatric problems and substance addiction. Britney will be singing her new record Womaniser on the show later this month, because Simon Cowell is a fan. He said: ‘I’m really excited about it, because she has got her act together and the new record is terrific. ‘She has come back from a very dark place and is a terrific artist.’
