Girl group Little Mix have revealed that their forthcoming new single, 'How Ya Doin'?', will be a "big surprise" for their fans.

The pop quartet spoke to Digital Spy about the track, which will be their fifth single to be lifted from their debut album, and when asked if the song has been changed in any way for release member Jesy Nelson teased: "You'll have to wait and see - there's definitely a big surprise coming. Be prepared!"

Leigh-Anne Pinnock added that the video for 'How Ya Doin'?', which is set to be released in iTunes in May, will be lively and entertaining:

"It's fun and there's lots of dancing. It's very animated and there's some amazing choreography. We all love dancing and each have our own style which works really well."
