Shy X Factor hopeful Amie Buck has been exposed as a lapdancer and tagged wannabe Curtis Moore a knife-wielding thug, as they both prepare for the bootcamp stage of the competition.

Amie, who fell apart at her audition on Saturday and was given a second chance, apparently earns £500 a week as a stripper in Newcastle – but told show bosses that she worked as a personal trainer.

A friend told The Sun: “Amie tends to just work weekends. But she is one of the more popular girls.

“She is really good at it and is a big hit with the blokes because she is so pretty – and has a great figure.”

Amie was put through to the show’s bootcamp round after judge Cheryl Cole joined her on stage to sing the Girls Aloud hit I’ll Stand By You.

Meanwhile, 16-year-old Curtis has been revealed as a thug who carried a knife as he terrorised his town with a gang.

Curtis, who wears an electronic tag, told producers he had turned his back on stealing and robbing houses – but his knife-carrying was not mentioned on Sunday’s show.

A former neighbour from Redditch, Worcs, said: “Curtis used to cause so much trouble in the shopping centre and carried a knife.

“He shoplifted mainly with lads older than him and even attempted stealing a bike the young owner was sat on in the middle of a busy bus station.”

The Sun reports that X Factor bosses have said they will not remove Curtis from the competition.
