As if we weren’t already sad enough to hear that Sienna Miller and Jude Law had called it quits, Tron: Legacy’s Olivia Wilde also announced her separation from Tao Ruspoli, her husband of eight years. A source told Us Weekly: “It was Olivia’s decision . . . for the typical Hollywood reasons. Her career has exploded and she saw being married is not as much fun. She feels she missed out on being single getting married so young, and wants to sow her wild oats.” Olivia’s star is definitely rising — she’s been busy attending awards season events (she has been appearing solo) and landed on the cover of Vanity Fair’s Hollywood Issue. Another reason we’re bummed about their breakup is that it means Olivia is no longer a real-life princess — Tao, a filmmaker, is the son of an aristocrat prince.
