On September 8, 2014, the boys announced the release of their fourth album, Four, on the Today Show. On September 14, 2014 the boys announced the first single would be "Steal My Girl". On September 28th, one day prior to the official release, the song was leaked on the internet.
The music video for the song was released on October 24, 2014. It features the band being directed by Hollywood superstar Danny Devito as they shoot a music video. Each band member is given a role to represent (Harry is "love", Niall is "light", Liam is "power", Louis is "danger" and Zayn is "mystery"). Liam is seen smashing a sign reading "inhibition" and leading a marching band. Zayn fights off sumo wrestlers. Louis interacts with a chimp named Eli. Niall dances with African dancers. Harry enters his scene through a door in mid-air that vanishes once he walks through. The video combines surreal imagery with different types of dancers and the group standing on a cliff performing the song. At the end of the video, everyone dances in the rain together, and Devito is satisfied with the footage filmed.
Since leaving the band, Zayn has expressed discomfort with being framed as "mysterious" (a title card in the beginning of the video describes him as such) saying this was a label forced on him and was untrue of his personality.
The song's opening closely resembles Journey's song 'Faithfully'. A reviewer felt the song sounded reminiscent of 1980s music, something that the band emphasized on their previous studio album. The lyrics fret over the potential for rivals to take the group's girlfriends away from them, and why they matter to them.
