Britain’s Got Talent winner George Sampson has parted company with his Ex Boss Simon Cowell.

Sources say things just weren’t working out between the young   dancer and the XFactor mogul.

After 14m viewers saw George’s victory on the ITV talent contest, the teenager’s career never took off as Simon would have liked, and he is now no longer working with Cowell’s Syco label.

A source said: ‘George just didn’t prove as marketable as Simon had hoped. When acts like George win the show, it’s much harder for them to forge a successful career compared with a singer, like Susan Boyle.’

And George, 16, who dazzled BGT audiences with his Singin’ In The Rain routine, did the relationship no good when he bad-mouthed Cowell last month, claiming the impresario wasn’t giving him any support.

He claimed he somehow ended up making a loss on his DVD, Access 2 All Areas, despite it being a successful seller.
