Marie Fredriksson, half of the Swedish pop rock duo Roxette and whose hit single “It Must Have Been Love” was featured in the 1990 film Pretty Woman, died Monday following a lengthy battle with cancer. Her management company confirmed her death to news outlets. Fredriksson was 61.

Fredrikkson joined with Per Gessle to form Roxette in 1986, a duo that went on to achieve international success with their albums Look Sharp! (1988) and Joyride (1991). Their breakout single “The Look,” reached number one on the Us Billboard Hot 100 chart in 1989. Their follow-up single “It Must Have Been Love” became the duo’s third number one hit in the U.S. after it was featured in the soundtrack of the 1990 romantic comedy Pretty Woman, starring Richard Gere and Julia Roberts. It ultimately became one of their best-selling releases, being certified gold or platinum in a number of countries. You can listen to the song in the clip from the film below.
