LOS ANGELES  - She’s not even a week old, but the baby daughter of Beyonce and Jay-Z has become the youngest person ever to be credited on the US Billboard chart.

The cries and coos of Blue Ivy Carter, who entered the world in New York on January 7, are featured on the new single “Glory” released by proud dad Jay-Z on Monday.

The track made its debut on the Billboard R&B/Hip-Hop songs chart this week at No. 74 — the chart’s highest new entry — with the newborn credited as “featuring B.I.C.”, Billboard said on Wednesday.
