From her early childhood, Beyoncé Knowles wanted to be more than a performer: she wanted to be a superstar. By the age of twenty-one, she had reached that goal, becoming world-famous not just in her chosen field of singing but also as an actress. After attaining wide success with the R&B group Destiny's Child, Knowles broke out on her own, releasing her solo debut, Dangerously in Love, in 2003. The single "Crazy in Love," featuring her boyfriend, now husband, rapper Jay-Z, was one of the biggest hits of the summer of 2003.
