Government name: Amethyst Amelia Kelly

Lots of women rappers have called themselves "bad bitches." But only Iggy Azalea actually named herself after her dog. "He used to go around and get in fights with all the other dogs," she explained in an interview with L.A. Record. "I used to try to rap with my real name [Amethyst], but it just doesn't rhyme; it has too many letters."
