Following their Twitter spat, Carolynne has now claimed that Christopher called her a 'c**t' during the rehearsal that saw him axed from Sunday night's final.
Carolynne has said that his 'mask' finally slipped as he lashed out at her, which allegedly happened after he found out he only had one line in the group performance.
“He came in and basically, because I didn’t say hi and kiss his a***, he called me a c***. Everyone heard it, even Jahmene, who was upset.
“I said to him, ‘Did you just call me a c***?’. He denied it but I heard him.”
Kye Sones, who had previously hinted at his strained relationship with Christopher, also backed up Carolynne's claims, adding: "He’s had a mask on for ten weeks and it has well and truly slipped off and shown him for who he is.”
The shaky scouser claims he didn't take part in Sunday's live final after being signed off with a sore throat but insiders claim show bosses refused to let him perform after his outburst, which was reportedly fuelled by alcohol.
However, despite recent reports Christopher is still insisting he is sick, and has taken to Twitter to tell of how his 'sore throat' has now developed into a chest infection.
He wrote: "good morning guys, still got a really bad chest infection. :-X still on antibiotics. love u all thank u so much 4 all ur love and support xx."
But a chest infection may be the least of his worries as he is reportedly facing the axe from the 'X Factor' tour following his antics.
