Abi Alton has been slammed by Kingsland Road.
The 'X Factor' group - who departed the competition at the weekend after losing in the sing-off to Tamera Foster - hit out at the 19-year-old hopeful for being "opinionated" and "sensitive".
Singer Josh Zare said: "She's not the most agreeable person in the world. She's just got expectations and not everyone lives up to them.
She's quite sensitive and we're very bantery lads, we like to play pranks and push the boundaries."
His bandmate Jay Scott added: "She's not sweet and she's not innocent - she's very opinionated."
And the quintet also revealed ousted group Miss Dynamix - who were made up of rejected solo acts - took a while to bond and get along.
Jay added to OK! magazine: "There were arguments about make-up brushes, girl things ... some bands are going to have more conflict than others.
"With them they came as solo artists. It took them a while to remember they were a band. They were starting to accept that so it's sad they've gone."
