"Two of Hearts" is a song by American singer Stacey Q, first issued as an independent 12-inch dance club single by On the Spot Records, then picked up by Atlantic after achieving regional sales.^[4] Written by John Mitchell, the song was Stacey Q's biggest hit; its global sales success fueled the recording of her debut album Better Than Heaven (1986), which included the song.^[5]

After the release of the album Playback (1983) with the band SSQ, Stacey Q began working with Jon St. James on her solo material. St. James brought her the song "Two of Hearts," suggesting that she record it. At first, Stacey Q refused to record a song written by someone else, but later she changed her mind.^[6] The single was co-produced by St. James who owned the recording studio, William Walker, and nightclub deejay Jeff Fishman. The artist and producers promoted the single, especially to Latin music audiences in Los Angeles and Miami. The song was picked up by Atlantic Records to be released as the lead single from Q's debut studio album Better Than Heaven (1986). They recorded the album in three weeks while the song was climbing the charts.^[4]

The song was prominently featured in the Facts of Life episode "Off-Broadway Baby" in which Stacey Q appeared as the character Cinnamon, a teenage singer largely modeled on herself; the episode ends with her performing the song in a radio station's sound booth.^[7]
