Singer James Arthur has been fired by music mogul Simon Cowell for lyrics which appear to glorify terrorism.

The "X Factor" winner's new song had a disturbing line: `I am going to blow your family up like I am a terrorist", which according to Cowell was not acceptable.

The 26-year-old singer has been kicked off Cowell's Syco label after recording just one album, reports mirror.co.uk.

Arthur took to Twitter to express his anguish.

He tweeted: "@SimonCowell I should 'shut up and put out records or else this?"

Arther was previously accused of homophobia by his former friend Lucy Spraggan in December who he then branded her an `attention seeker.`

He was given a final warning by Syco bosses after embroiling in an online spat with glamour model Teddy Edwardes over lewd messages in February.
