Brooklyn Blue, 24, had successfully got through three rounds of auditions under her real name, Becky Constantinou, and had been shortlisted to perform for Simon Cowell and the other judges until a member of the security team at Wembley revealed her secret identity to ITV bosses.

The busty blonde - who has admitted to romping on camera with 700 men and 300 women - said: "The guard came up to me with a knowing smile and said, 'I know you from somewhere, you're that Brooklyn girl'.

"A few days later I got a call from the show makers asking if I'd done any modelling and my stage names.

"It was clear I'd been grassed up, but I did my best to dodge the questions. I then had a long think and decided to come clean in an email.

"They phoned me back to say I'm out. I'm devastated."

Becky - who previously dated former 'The Only Way Is Essex' star Kirk Norcross - thinks it's unfair she's been kicked off the show, especially as she'd spent hundreds of pounds on signing lessons in a bid to impress the judges.

She told The Sun newspaper: "I know 'X Factor' is a family show, but porn shouldn't define who I am. I was never going to put on a sex show for Simon."

An 'X Factor' source confirmed Becky has been dropped from the competition, saying: "After checks, she was told she wouldn't be going further."
