It seems all the praise from the judges has gone straight to X Factor hopeful Misha Bryan's head. The 19-year-ol d singer, who Gary Barlow branded "incredible" on last week's show, has been dubbed "the diva from hell" backstage.
She's got so bad, mentor Kelly Rowland threatened to kick her off the show if her attitude failed to improve, The Sun reports.
Misha supposedly boasted to the other finalists: "I've already won."
A source told newspaper: "Misha is out of control and Kelly just snapped. She told her that unless she packs it in, she'll be sent packing herself.
"It's one thing to give it the big 'I am' with the other wannabes, but it's totally out of order to be rude to people who work on the show.
"Kelly is a lovely woman but when the s*** hits the fan she gets tough - and she got very tough with Misha."
The singer wowed at her first audition and has continued to win praise from the panel. The talented teenage is currently one of the favourites to win the show.
Kelly forced Misha to sheepishly apologise for her outbursts, which also included rants at the show's vocal coaches and production staff.
