• Concerning the penning of the song, Smith told Black Entertainment Television that he was in Los Angeles when he got a call from the song's co-producer Antonio Dixon, for whom he has been writing for years, telling him that they were going to do some work with Beyoncé. Smith wrote part of the song during his journey to the L.A. studio to join the rest of the team. Once he arrived at the studio, Dixon joined him and they completed the song together. After hearing the record, Babyface made some modifications, according to Smith: "You know—a word here, a word there, a melody here, and all of a sudden the record had a completely new life. He [Babyface] is absolutely masterful at what he does. And I'm super honored to be working with dude."
