The song, written by Dennis Matkosky and Michael Sembello, and produced by Ross herself, was the second release from her Platinum-certified album, Why Do Fools Fall in Love.

The song talked 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" became another smash for Diana, reaching #2 on the Soul chart and peaking at number eight on the Billboard Hot 100 It became her second top 10 hit after leaving her longtime label, Motown, in the summer of 1981.

The music video was played on BET but rejected by MTV. It showcased the glamorous diva lip-syching the song and during the break, she danced with the video dividing her in double vision as she spun around. Despite the rudimentary production values, it was an early BET favorite. However, it was conspicuously left off her best-selling VHS - and later DVD - compilation "Visions Of Diana Ross".

"Mirror Mirror" is also notable as one of the few songs Diana sung both lead and background vocals.

"Mirror Mirror" was performed during Diana Ross' iconic live concert in front of 800,000 people, Diana Ross Live in Central Park.

"Mirror Mirror" was performed on her recent 2010 concert tour. It was the first time it was performed in over 15 years.
