"Mirror, Mirror" is a song by American singer Diana Ross. Written by Dennis Matkosky and Michael Sembello, and produced by Ross, the song was released as the second single from her Platinum-certified album Why Do Fools Fall in Love on December 11, 1981, by RCA Records.
The song talks of a love lost that the singer was going through and her deliberately asking herself while looking in the mirror why she allowed the love "to fall" apart, referencing the Wicked Queen's chant to the Magic Mirror in Snow White and the Seven Dwarfs: "Mirror, mirror on the wall". "Mirror Mirror" is also notable as one of the few songs that Ross sung both lead and background vocals.
The accompanying music video for "Mirror Mirror" was played on BET, but was rejected by MTV. It showcases Ross lip-synching the song and during the break, she dances with the video dividing her in double vision as she spins around. Despite the rudimentary production values, it was an early BET favorite. However, it was conspicuously left off of her VHS, and later DVD, compilation Visions of Diana Ross.
"Mirror Mirror" reached number eight on the main US Billboard Hot 100 chart and reached number two on the US Billboard soul chart.
