'X Factor' boy band Union J may be sued by a former manager who wants five per cent of their earnings.
Julian White claims he put the original line-up of the group - Josh Cuthburt, JJ Hamblett and Jaymi Hensley - together under the name Rewind, which he set up in 2011.
However, he says as soon as they got some interest from music producers and the press they ditched him and signed up with Brian Dreelan under the name Triple J.
Since then they added new member George Shelley and renamed themselves Union J.
He told The Sun newspaper: "I made these lads and we signed an agreement for a contract. Next thing I know they've changed their name to Triple J and auditioned for X Factor with Blair as their manager.
"They got all aggressive when I asked them why they'd gone. But I've consulted my lawyer and as soon as they start earning I'm coming after them for five per cent of their earnings.
"I'm told I have a very good case."
However, the new manager of the band says the boys are confident no such problem should come from their old manager.
He said: "Union J are confident that the ex-manager of Triple J has no contractual claims over the band."
