Many have speculated that Jay-Z and Beyonce's newborn daughter Blue Ivy Carter would persue a music career later in life - but it seems she's appearing on a song ALREADY!
Mr Z has posted a new song entitled 'Glory (B.I.C.)' to his official website, with the message: "Life just got REALLY good".
Gossip Cop reports that the baby heard crying on the track is little Blue Ivy herself.
The song also appears to contain the revelation that Beyonce had previously suffered a miscarriage.
Neither parent has yet made an official comment on the birth of their first child, but celebrities including Beyonce's friend Gwyneth Paltrow have been tweeting their congratulations.
After initial confusion over whether the bubba's name is Ivy Blue, it has since emerged that her name is Blue Ivy.

Mum's a pop idol, Blue!
