X Factor star attacks Simon Cowell on Twitter

X Factor winner, James Arthur is at it again on Twitter and this time he’s decided to have a go at his boss, Simon Cowell.

The singer was responding to reports that he is featured in the musical, I Can’t Sing which is based on Simon Cowell’s role as a judge on X Factor.

James went onto to tweet an article claiming the musical was based on him saying: “@SimonCowell I should ‘shut up and put out records’ or else this?”

The Recovery singer then went onto tweet about how he expected the media would react to his latest tweet: “Cue more media bullying.”

It isn’t the first time James has took to Twitter to lash out but he might want to take it easy on Simon since he’s singed up  to Cowell’s label, Syco Music.
