The notorious name-changer has taken to calling himself Ciroc Obama, and for good reason: Through his vodka deal with beverage giant Diageo, Diddy receives an annual cut of profits and a big chunk of cash if the Ciroc brand is ever sold.

Other notable names on the list include Interscope's Jimmy Iovine ($400 million), movie director/producer Michael Bay ($410 million), Dropbox CEO Drew Houston ($400 million) and Twitter creator Jack Dorsey ($650 million).
