Beyonce and Jay-Z’s baby girl is making pop chart history in the U.S. after becoming the youngest act ever to be credited on a Billboard Hot 100 hit. Little Blue Ivy Carter was just hours old when proud dad Jay-Z recorded her crying and added it to the end of his new tune “Glory,” which he released to the internet recently.. and the song is already a hit. It will debut at 74 on the new Billboard countdown when it’s officially released on Thursday (and that’s a new record for the artist credited as B.I.C.) She trumps Stevie Wonder’s newborn Aisha, who appeared on his “Isn’t She Lovely”, because the soul man never officially credited his baby as a collaborator on the record.
