The four-piece girl group are seen thanking fans straight after their win on the ITV1 series and celebrating with the other contestants.

Little Mix have released behind-the-scenes footage from their victory on The X Factor last weekend.

The four-piece girl band beat fellow hopeful Marcus Collins to be crowned 2011 champion on the ITV1 series on Sunday (11th December) and are seen in the video celebrating their win with friends backstage.

"This is just the start," Little Mix mentor Tulisa Contostavlos says in the clip. "Winning The X Factor is one thing but now they have a career ahead of them, I'm gonna be with them every step of the way."

"They work hard and they've become sisters and I'm so proud of them," eliminated contestant Craig Colton added. "Well done!"

Tulisa has since revealed plans to have Little Mix contribute to a track on her upcoming solo album, expected out sometime in 2012.
