Tulisa: Little Mix have great future ahead

Tulisa Contostavlos says Little Mix's debut single is "a formality".

The N-Dubz singer mentored the group – who saw their cover of Damian Rice's 'Cannonball' reach number one in the UK singles chart yesterday – to victory on 'The X Factor' and thinks they can go on to establish their own identity now they have released their first song.
