Just ask Mary-Kate Olsen. A year after Paris Hilton stole her prior heir -- of the Greek shipping variety -- the pint-sized bag lady is "quietly dating" oil heir Maxwell Snow, in the hopes that, if Paris Hilton doesn't catch word of his existence, she can't fuck him. But Paris Hilton can fuck anything. Watch your back, MK.
Snow is from some famous Texas oil family, and is Uma Thurman's nephew (Did you know Uma Thurman came from oil money? I didn't.)
