Christina Aguilera - AOL Music

Aguilera has the true Sagittarian spirit, her high energy vocal beats prove this. As a child, she was known locally as the little girl with the big voice. According to VH1's Driven, this label eventually backfired on her. When competitors learned they would be up against her in any given week, they immediately backed out, prompting insiders to claim it was "like sending a lamb to the slaughter."
