Janowicz filed divorce papers Tuesday in Los Angeles, citing irreconcilable differences with the Once Upon a Time and Lost star.
The papers say the couple, both 32, separated last November. They also list their date of marriage as June 19, 2003, although their public wedding ceremony took place three years after that, on June 26, 2006.
The pair had previously planned to divorce in 2009, but the papers were never finalized. This was the first marriage for both. They have no children.
The pair met through friends, de Ravin told PEOPLE, “which is the best way to meet someone, isn’t it?” she said.
