The single version of the 'Sticks + Stones' track features an additional verse rapped by 15-year-old US X Factor runner-up Astro. The 'Stop Looking At My Mom' hitmaker features briefly in the video, which sees Cher playing the role of a slightly bitter ex-girlfriend.
Astro tweeted: "To all my UK and European #ASTROnauts, check out my homegirl @cherlloyd's new video featuring ya boy. It's #DOPE!"
'Want U Back' is out on February 12 and you can watch the music video here.
