James has apparently pushed things too far and his latest lyrics, which reportedly include a reference to a terrorist act, and Simon has “lost patience” with the Middlesbrough-born singer.
In mixtape track ‘Follow The Leader’, James raps, “Look at what you do to me, I’m crying over stupid s***, you’re such a f***ing homophobe, wish I’d never let you in, to think that I was thinking maybe I should let you live, I’m gonna blow up your family like I’m a terrorist.”
James has already taken to Twitter to defend the lyrics, stating that they are actually taken from a letter from a “demented fan”.
“The song "follow the leader" from the mixtape is not promoting terrorism, it's a story, a reciting of a Stan Esc letter from a demented fan,” he tweeted.
On another track, James reportedly brags about taking drugs, singing: ““I can smoke my weed, you can drink rosé, all day.”
“It’s a very sad and messy way for this to all end.”

Syco Records boss Simon has apparently had enough
This latest incident is another in a long line of mishaps, which have included publicly sacking his PR team via Twitter and becoming embroiled in a row over homophobia when he used a homophobic slur in another rap.
Fellow ‘X Factor’ contestant Rylan Clark previously has defended James, stating that he thinks his pal is “insecure”.
