The crying sounds of the couple's baby has made her a record breaker on the US chart rundown.
Beyonce and Jay-Z's newly born daughter Blue Ivy Carter has broken the record for the youngest person to ever feature on the US Billboard chart.
The couple's child features on Jay-Z's track 'Glory', which he released through his own social site Life and Times earlier this week.
The song is a dedication to the rapper's first child, as he raps: "Words can't describe the feeling for real, baby I'll paint the sky blue, my greatest creation was you."
Cries from a baby can be heard at the end of the track with Jay crediting B.I.C, presumably a reference to the initials of his new daughter.
The track will enter the Billboard Chart at number 74 next week following its popularity once it emerged online.
Meanwhile, Jay-Z and Beyonce are reportedly looking into making a musical first by becoming the first artists to shoot a music video in space.
