Will Smith — $42 millions, Californie

He was once the Prince of Bel-Air, but today he’s the king of Calabasas, California. The house sits on a lot so huge, it has, believe it or not, its own zip code. The Pinkett-Smith clan bought this house for 20 million dollars, with basketball courts, golf courses, tennis courts, a gigantic garage and also a recording studio. It seems that the house would be on the market for 42 million, a price granted thanks to the renovations that the couple undertook while they still lived there.
