Christopher Maloney branded Carolynne Poole a "c***" during a row on The X Factor final this weekend.
Country singer Carolynne was eliminated from the first live show, while Chris finished third on the series on Saturday night.
Sunday was meant to see a group performance from both of them, as well as the other live show finalists, but Chris left rehearsals after clashing with the other contestants.
Carolynne said: “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.”
Giving her side of the story to The Sun, she continued: “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.’”
And Carolynne claimed that the X Factor bubble had turned cruise ship Chris into a diva.
She explained: “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.”
