De Ravin and Janowicz, both 27, dated for four years before they married in June 2006 in Australia and moved to Los Angeles. "Emilie and her husband have filed for divorce," her rep, Jeff Raymond, tells PEOPLE. "They have recently been living separately and remain friends."
The actress this summer films Remember Me with Robert Pattinson, and will return to Lost for its sixth and final season. She's also in the Michael Mann-directed Public Enemies with Johnny Depp.
Janowicz has appeared in The Nature of Space & Time and On the Doll.
