Pop icon Prince has died at his home in the US state of Minnesota at the age of 57, gossip site TMZ reports.
Citing "multiple sources connected to the singer," TMZ said the musician's body was discovered Thursday morning at his mansion outside Minneapolis.
Law enforcement authorities said they were investigating a death at the compound, according to news reports.
Jason Kamerud, sheriff's deputy for Carver County, said authorities would not give information on the identity of the deceased until next of kin had been notified, according to the Minneapolis Star Tribune.
Prince was one of the most acclaimed musicians of his generation, a producer, composer and performer famed his inventive, sensual style with hits including Purple Rain, Little Red Corvette and Kiss.
He won seven Grammys and was inducted to the Rock and Roll Hall of Fame in 2004.
Prince reportedly became ill enough last week to force his plane to an emergency landing, according to TMZ. He appeared at a concert the next day, and his publicists told media he was recovering from flu.
