Olivia Wilde is no longer a real-life princess.  The 26-year-old TRON: Legacy beauty and her husband Tao Ruspoli have mutually agreed to separate after eight years of marriage.  Wilde's rep wouldn't go into detail about the separation but confirmed the tragic news. 

"They have been living apart after trying for quite some time to make their relationship work," a source told People.
