1999-2001: Rise to fame
Simpson released her first single, "I Wanna Love You Forever," which peaked at #3 on the Billboard Hot 100 in 2000. Soon afterward her album Sweet Kisses was released. Simpson toured with boy band 98 Degrees to promote her new album. She was given a role in the music video for 98 Degrees' hit song "My Everything," playing Nick Lachey's love interest. At that time she and Lachey began dating. After dating for two years the couple cooled their relationship, stating that the "break" allowed them to concentrate on their music careers. Then on September 11, 2001, Lachey was supposed to be flying out of New York City with his group 98 Degrees. When Simpson heard of the attacks on the nation coming from the airport she immediately phoned Lachey to learn his whereabouts. After this scare the couple rekindled the relationship.
