This past weekend Mary J. Blige performed at the iHeart Music Festival in Las Vegas and to everyone's surprise she was joined by the legendary Prince.
Blige yelled to crowd, "“I got a real good friend in the building. He’s one of the most amazing artists to ever walk the earth,” before Prince hopped on stage.
Rocking his new fro and unique gold plated shades, Prince performed "Sweet Thing" and "Nothing compares To You" with Blige.
