British pop band Little Mix have confirmed that they are to record Word Up, the official single for the upcoming biennial Sport Relief.

Taking to their Twitter account earlier this evening, the pop quartet announced “We are really excited to announce this years official @SportRelief Single is called ‘Word Up’ sung by….. US!!”

It is yet to be confirmed whether Word Up will be an entirely new single or a cover of the 1986 hit of the same name by US band Cameo.

More as we hear it.
