Songfacts®:

• The lead single from girl group The Saturdays' fourth studio album signaled a new dance-pop direction for the five-piece. The song, which was released on May 22, 2011 in the UK, was described by Pop Justice as, "a bit Black Eyed Peas-esque, feels a tiny bit like Kelis and Rihanna, and has a strong, propulsive energy that builds throughout the tune."
• The song was produced by prolific hitmaker Steve Mac, who has credits on numerous UK #1 singles and albums for artists such as Westlife, Gareth Gates and Leona Lewis. He also previously helmed The Saturdays' hit single "Ego." Norwegian songwriter Ina Wroldsen, who has penned many of The Saturdays' hits, is the credited songwriter.
• The song's music video was filmed in Los Angeles in April 2011 and finds the girls dressed in office attire before letting their hair down in a club. It was the second clip that the girls had recorded in LA, after "Higher."
• Here's what Mollie King and Una Healy from The Saturdays had to say about the track during an interview with Digital Spy:
  
  Mollie: "It's obviously still pop, but it's got more of a dance beat behind it. It's about when you step on to the dancefloor and transform into a completely different person - when you turn into a bad girl!"
  Una: "Dance is massive at the moment so it's a dance track, but it also has something unique behind it. It's got this drop-out chorus where it's just the beat and you can only hear our voices - there aren't many tracks like that, so it's a bit different."
