Fans have been reacting to leaked audio of Blue Ivy Carter’s rap on her father JAY-Z’s album 4:44.
The song, called Blue’s Freestyle/We Family, is one of three bonus tracks released with the physical edition of JAY-Z’s platinum-selling album.
Other bonus tracks on the CD of 4:44, out today, are called Adnis and ManyFacedGod (featuring James Blake).
But it was the 45-second clip of five-year-old Blue’s rapping that sent Twitter fans crazy.
Not all of Blue’s lyrics are that clear – but that didn’t matter to most fans.
This isn’t actually the five-year-old’s debut – she featured on her dad’s 2012 song Glory, making baby noises.
It made her the youngest person ever to be credited on the US singles chart.
