Their first album, Not Like Other Girls, was first released in spring of 1998, along with first single This Is How We Party. Internationally, the group was managed by Simon Fuller, and the group became an international hit with chart positions in Europe, Japan, Australia and the U.S. alike. The girls also toured with The Backstreet Boys and won two Danish Grammy awards for their debut.
In 2010, Line released her first solo album under the artist name Saseline.
