Simon Cowell has reportedly BANNED Niall Horan from performing his solo material on The X Factor .
The TV judge, who discovered the Irish signer when he put together One Direction on the show, is upset over him snubbing his solo record deal and signing with Universal.
According to The Sun on Sunday newspaper , there is 'zero chance' he will be invited onto one of the live shows to perform his track This Town, while Liam Payne is also said to be blacklisted after he chose to go with a rival label.
