The girl group mashed the track with Lumidee's 'Never Leave You (Uh Oh)' for an SB.TV session in support of their debut album DNA.
Little Mix released their first studio album earlier this week, and it started at number four in the midweek chart update.
The collection features chart-topping hit 'Wings', along with recent single and title track 'DNA'.
The set also includes a collaboration with TLC's T-Boz on 'Red Planet' and a co-write with Girls Aloud's Nicola Roberts on 'Going Nowhere'.
Little Mix recently revealed their aspirations in following One Direction's success in the US, and plan to promote their debut record there in 2013.
