Seven-time Grammy winner Prince, who was known for megahits like “When Doves Cry” and “Purple Rain,” has died at the age of 57.

Prince was found dead in his Paisley Park estate in Chanhassen, Minn. on Thursday. 

The singer's publicist confirmed his death to Fox News. No details of his death were released, but the Carver County Sheriff's Office said officials are "investigating the circumstances of his death."

"It is with profound sadness that I am confirming that the legendary, iconic performer, Prince Rogers Nelson, has died at his Paisley Park residence this morning at the age of 57," his rep wrote in a statement.

Prince had been rushed to a hospital last Friday morning in Illinois and was released several hours later. His rep told TMZ he had been battling the flu for several weeks. 

Prince was born in Minneapolis, and broke through in the late 1970s with the hits "Wanna Be Your Lover" and soared over the following decade with the albums as "1999" and "Purple Rain." 

The title song from "1999" includes one of the most widely quoted refrains of popular culture: "Tonight I'm gonna party like it's 1999."
