Another Hollywood star is heading for divorce court. Olivia Wilde and her husband, Tao Ruspoli, have separated, according to People.

The couple had been married for eight years and the decision to split was reportedly a mutual one. "They have been living apart after trying for quite some time to make their relationship work," a source told the magazine.

Representatives for the actress confirmed news of the separation to MTV News but declined to comment further.

Wilde, 26, married the Italian prince when she was 18. While his family owns Rome's Palazzo Ruspoli, Wilde has been burning up the big screen thanks to high-profile roles in films like [article id="1654185"]"Tron Legacy"[/article] and "Cowboys & Aliens." She's also had successful small-screen parts on shows like "The O.C." and "House M.D."

And Wilde's star is on the rise: She appears in the Vanity Fair Hollywood Issue out this month and recently made a scantily clad appearance in FHM France.

Sources say the pair have been separated for some time now, and when Wilde appeared on the cover of Women's Health in December, she opened up about married life, noting that anything could happen to the couple. "You're not thinking, 'We must be perfect!' " she admitted. "It was, 'Hey, isn't this an optimistic thing to do? And if it lasts, we're lucky.' "
