The 'Remedy' hitmaker - who is to release his third studio album 'Growing Up In Public' this September - was forced to drop the 'X Factor' winner from a track following a string of public controversies surrounding his use of homophobic lyrics and online Twitter rants, reports The Mirror newspaper.
Professor Green, 30, said: ''James Arthur was on that record. But then he just kind of imploded, didn't he? It's a shame, when I met him he was a cool guy but he just upset so many people.
''The label was just like, 'It's not happening', and I can't fight the people who I need to support me.''
However, the 'I Need You Tonight' hitmaker remains fond of James, 26, and hopes that the 'Impossible' singer will be able to get his career back on track.
He explained: ''When I met him, I thought he was a nice guy, so hopefully he can just bring some of that back and get people to focus on the music and maybe he can too, rather than getting concealed by all the bulls**t.''
Affleck was recently confirmed to be NOT directing 'The Batman', despite many rumours that he would be doing so.
