'Dub On The Track' is taken from her debut album Sticks + Stones, released last month.
The song includes features from underground artists Mic Righteous, Dot Rotten and Ghetts, who also all appear in the accompanying video, which premiered on SBTV.
The clip is a stripped-back affair, which sees the 18-year-old in a Buffy the Vampire Slayer T-shirt and camouflage shorts hanging out in an underground den.
The X Factor 2010 star recently admitted that she had a poor attitude throughout her time on the singing competition and that she had to learn the hard way by toning her personality down.
Sticks + Stones reached number four on the UK album chart back in November.
