Brandon Davis, grandson of oil tycoon Marvin Davis
Davis, a 32-year-old oil heir and frequent pal of Paris Hilton, is commonly in the tabloids for drug charges infractions, alleged nightclub brawls, and crude, often inappropriate humor.
He famously dated actress Mischa Barton, and then referred to her as a "heifer" on Twitter when they broke up in 2010 and was caught on tape soon after calling Lindsay Lohan "a fire crotch."
Though the personal life of this American socialite is somewhat disheveled, Davis has shown glimmers of business acumen.
In 2011, he brokered what many consider to be one of the largest real estate deals in Hollywood history, the $85 mansion deal with Berni Ecclestone's daughter Petra, according to The Daily Mail.
Davis, or Greasy Bear, as he's often called in the tabloids, is worth an estimated $55 million.
