"Mirrors", also titled "Mirrors (I Don't Wanna Lose You Now)", is a song recorded by American singer-songwriter Justin Timberlake for his third studio album, The 20/20 Experience (2013). First conceived in 2009, the track was inspired by his relationship with Jessica Biel and the marriage of his grandparents. It is an eight-minute-long mid-tempo progressive pop and R&B ballad. Timberlake wrote and produced the song with Timothy "Timbaland" Mosley and Jerome "J-Roc" Harmon, with additional writing from James Fauntleroy. The accompanying music video, directed by Floria Sigismondi, was released in March 2013 and depicts a tale of two lovers through several decades.
"Mirrors" was issued as the second single from The 20/20 Experience in February 2013. 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. It peaked at number two on the Billboard Hot 100 and topped the Mainstream Top 40 in the United States. "Mirrors" was ranked at number six on the Year-End Hot 100 chart. The song was met with positive reviews by critics upon release and received a Grammy Award nomination for Best Pop Solo Performance. Its music video won two MTV Video Music Awards, including Video of the Year. As of 2018, the song has sold over 3.9 million downloads in the US.
Timberlake performed "Mirrors" on television shows including Saturday Night Live and the 2013 MTV Video Music Awards as part of a medley number.
