During an interview with Billboard magazine, Harmon recalled how the song was conceived in 2009, during the recording sessions for Timbaland's third studio album Shock Value II (2009), "He's like, 'I'm gonna save this one, and this is gonna go on my album.' We never knew when he was going to put it out – we were like, 'Aw man, you're in movies now!' We could have waited another 10, 15 years. "Mirrors" was written and produced by Justin Timberlake, Timothy "Timbaland" Mosley and Jerome "J-Roc" Harmon, with additional writing from James Fauntleroy.

It peaked at number two on the Billboard Hot 100 and topped the Mainstream Top 40 in the United States. It went on to top the Australian Urban, Bulgarian, European, Lebanese, Polish, South African and United Kingdom singles charts, being Timberlake's fourth number-one single in the UK. "Mirrors" was issued as the second single from The 20/20 Experience on February 11, 2013. The accompanying music video, directed by Floria Sigismondi, was released in March 2013 and depicts a tale of two lovers through several decades.
