STOCKHOLM (AP) — Marie Fredriksson, the female half of the Swedish pop duo Roxette, has died at age 61, her management agency said today.

Fredriksson formed Roxette with Per Gessle in 1986. The two released their first album the same year and went on to achieve international success in the late 1980s and 1990s with hits including “The Look” and “It Must Have Been Love.”

The Dimberg Jernberg agency said Fredriksson died Monday “of the consequences of a long illness.”

It “is with great sorrow that we must inform you that one of greatest and most-loved artists is gone,” the firm said.
