It looks like Blue Ivy is following in her parents' footsteps. The five-year-old made her freestyle rap debut on Jay Z's "4:44" album in one of the bonus tracks. "Everything everything this my only single thing/ Everything I hear is my answer/ And if you think I say, then / I never hear that, I be in the posse," Blue raps. Blue Ivy's verse ends with "boomshakalaka."
