Prince's final concert was at Atlanta's Fox Theatre a week ago, and the show was a makeup concert due to the artist having the flu earlier this month. On Saturday, Prince held a dance party at his Paisley Park estate in Chanhassen, Minn., and briefly spoke to the audience. The event came a day after his plane reportedly made an emergency landing due to Prince being dehydrated, the Star Tribune reports. An editor who attended Saturday's event wrote that Prince "just wanted to demonstrate that reports of his dire health were greatly exaggerated." Prince's cause of death hasn't been determined.
