The song is a piano ballad that has the guys lamenting about those who want to steal their girlfriends away. Co-written by One Direction's Louis Tomlinson and Liam Payne (who also wrote "Fireproof" together) along with Ed Drewett, Wayne Hector, Julian Bunetta and John Ryan, "Steal My Girl" is a more serious ballad than we've previously heard from the guys.

"Everybody wanna steal my girl/ Everybody wanna take her heart away/ Couple billion in the whole wide world/ Find another one because she belongs to me," they sing on the chorus.
