Blue Ivy's parents, Beyonce and Jay-Z, are known for selling out shows and crafting chart-topping albums, so it's not a surprise that the newborn has already set a Billboard chart record of her own. According to Billboard, since proud dad Jay-Z released his song "Glory" on Monday, it's already entered the R&B/Hip-Hop songs chart at No. 74. And since four-day-old baby Blue drops a guest verse of cries following her delivery on January 7, and is credited for her contribution as "B.I.C.," the newborn is now the youngest person ever to land on a Billboard chart. (If you're wondering how Blue beat Stevie Wonder's daughter Aisha, whose first cries can be heard on Wonder's "Isn't She Lovely," Billboard notes that Aisha was never credited, and the song didn't reach a chart until 1977, two years following her birth.) Jay-Z's touching tribute to his "greatest creation" not only revealed his joy at welcoming his daughter into the world, but also reflected on the superstar couple's previous attempts at conception that ended in miscarriage. "Last time the miscarriage was so tragic, we was afraid you disappeared," he said in a verse, "but nah, baby, you magic." Magic, and now with a chart-climbing single.
