Pop singer best known as the founder of 1990s pop band Ace of Base, which she formed with her sister Jenny, her brother Jonas, and her friend Ulf Ekberg.
She was the principal lead vocalist for many of the group's early singles off their first album, after which she began splitting singing and songwriting duties with Jenny.
She became a recluse after the release of the group's second album, The Bridge, hiding in live performances and avoiding camera appearances. Jenny took charge of the group in her absence.
She kept all details of her personal life quiet, unlike the other members of Ace of Bass who were open about their lives and relationships. She was known to be multi-lingual, speaking Swedish, English, German, Russian, French, and Spanish.
She and the rest of Ace of Base were frequent guests on BBC's Top of the Pops, the long-running series hosted by Fearne Cotton, among others.
