Little Mix have revealed that they are currently hard at work on their debut single and told fans to expect something 'completely different' from the release.

The X Factor winners performed at the National Television Awards last night (Jan 25) and spoke to Caroline Flack during the ITV2 aftershow, 'The Party'. Speaking to Harry Styles other half, they were asked what they had been up to so far in 2012, to which Jesy Nelson replied:

"We've been writing for our single and it's just been non-stop."

Pressed for details of the track, Leigh-Ann Pinnock then added; "We've been in the studio loads, expect something completely different that you've never heard before. It's going to be wicked."

The girls also spoke about Tulisa, who collected the award for Best Talent Show alongside Gary Barlow on behalf of the X Factor last night.

"Tulisa keeps us calm, we were so nervous. Then I saw her face and I was like, "Right, it's all good."
