SINGER Prince has died at the age of 57, his publicist said.

His body was discovered at his Paisley Park compound in Minnesota, where his recording studio is located early on Thursday.

Prince, whose real name is Prince Rogers Nelson, suffered a medical emergency earlier this month that forced his private jet to make an emergency landing in Illinois.

The Carver County Sheriff's Office tweeted that an investigation was under way on Thursday morning.

They told the Minneapolis Star Tribune that the identity of the deceased was being withheld until next of kin had been notified.

They tweeted: "Deputies are on scene of a death investigation at Paisley Park in Chanhassen. More info to follow."
