Christopher Maloney called Carolynne Poole a **** when she didn't say hello to him, the brunette star has revealed.
The country singer claims the former cruise ship crooner was abusive to her at rehearsals for 'The X Factor' final on Sunday (09.12.12) - where he reportedly turned up "clearly drunk" - because she "didn't kiss his a**e".
Carolynne - who was voted off the show in the first week - said: "After 10 weeks the mask came off, it was like he couldn't keep it up any more.
"He came in and basically, because I didn't say hi and kiss his a***, he called me a ****. Everyone heard it, even Jahmene, who was upset.
"I said to him, 'Did you just call me a ****?'. He denied it but I heard him."
The brunette beauty also hit out at the way he treated staff on the ITV1 show and said the Liverpool-born singer - who is thought to have been annoyed he only had one line in the group song - made a dig at her appearance during rehearsals.
Speaking at the 'X Factor' final afterparty following James Arthur's victory, she added to The Sun newspaper: "We were rehearsing the group song and he wouldn't even stand next to me.
"He came over and looked me up and down and said, 'You need to do something with that.'
"When you get onto 'X Factor' you go into this bubble where everything is done for you.
"There are people that sort everything for you, get whatever you need, basically wipe your a**e for you.
"These people work so bloody hard to make sure you're OK and you can't treat them like this. He was always like, 'Do this, do that, get me this'. It's just not how you treat people."
Former 'X Factor' contestant Kye Sones agreed that Christopher - who claims he couldn't compete in 'The X Factor' final due to a "sore throat" - had shown his true colours.
He explained: "He's had a mask on for 10 weeks and it has well and truly slipped off and shown him for who he is."
Christopher's position on the lucrative 'X Factor' tour is in doubt following his comments, and a source said bosses are "90 per cent sure" he won't be in the line-up.
Christopher revealed he had been inundated with offers just "20 minutes" after being booted off the competition on Saturday (08.12.12).
His father says the crooner is now heading to Tenerife for a week to escape the commotion.
