The Jumper costars are no longer engaged and have ended their three-year romance, Bilson's rep confirmed to E! News Monday.
Their last public splash as a couple was a trip to Christensen's native Vancouver for the Winter Olympics, where they were snapped at a hockey game looking, to put it mildly, less than thrilled to be there.
People, which first reported the "break" turned permanent split, quotes a source saying, "It just wasn't working out" and Bilson is "focusing on her career, spending time with her family and just moving forward."
The former O.C. star met Christensen on the set of 2007's Jumper .
They got engaged in December 2008, choosing not to make a big announcement about—or ever really confirm—it. But, gotcha, the following February, Bilson was overheard telling a fellow passenger on a flight from L.A. to New York that she was engaged.
