Rapper Juice WRLD has died at 21

Chicago police confirmed to the Chicago Sun-Times that the 21-year-old suffered a medical emergency at the airport after disembarking from his private jet around 2 a.m.

Juice - who once toured with Nicki Minaj - had been celebrating his 21st birthday a little under a week after his death. 

Celebrities messages of grief have poured in overnight, with Ellie Goulding, Chance the Rapper and Kehlani all expressing their sadness over the tragic death. 

This is a developing story, more to come.
