One contestant who wished to remain anonymous told The Sun: “Christopher could not be any more different off camera.
“He isn’t nervous at all and is actually quite big-headed.”
Axed Carolynne Poole - who was voted out of the show last weekend - chipped in too, claiming that Christopher keeps to himself at the X Factor hotel.
She said: “I didn’t see he was shy. The reason people say things about him is he is a confident, bold person so they are surprised when they see the nerves.”
Well, being a confident person doesn't necessarily mean you can't suffer from stage fright, does it?
Chris is also facing accusations of diva behaviour - after Louis Walsh, Tulisa and Nicole Scherzinger all said that they had heard tales of his 'diva antics' backstage on Sunday's edition of The Xtra Factor.
But don't worry Christopher lovers - Gazza Barlow told them off for gossiping. The hero.
What do you think scapers - nasty rumours, or hidden truth? Watch our interview with Christopher here, where he talks about combating his nerves.
