Just last month, Hollyscoop reported that the two had broken up, or as they put, "were taking a break."
But just weeks later, it appears the split is permanent. "Yes, the engagement is off," Bilson's rep explained, but didn't offer up any further details on the breakup.
Sources say however that distance was reportedly one of the main reasons for the split. With Bilson primarily in L.A., and Christensen in Canada, "It just wasn't working out," says a friend of the actress.
Now Bilson is "focusing on her career, spending time with her family and just moving forward," adds the friend.
As for Christensen, he was most recently spotted with actress Sophie Monk. The two were seen leaving LA hotspot Boulevard 3 after the Takers premiere last week.
We hate to say it, but it's a little bit of a downgrade!
