X factor: Tulisa abused

Tulisa Contostavlos, the N-Dubz singer, was called a "scumbag" after she stepped in to stop George Gerasimou's rendition of 'Give Me Everything' by Ne-Yo at 'The X Factor' auditions. Staff then quickly jumped up to intervene after he began to approach the judge's desk in front of 10,000 others at the London O2 Arena...

Gerasimou's aggressive style didn't get him much further back in 2009, when he had a run-in with the panel after appearing on the show. That time, he told Simon Cowell to "shut up" before storming off stage after the judge criticised him.
