The former "Star Wars" actor and "O.C." starlett have broken off their engagement, reports People.
"Yes, the engagement is off, " said Bilson's representative in an interview with the magazine. The rep declined to give further details of the split.
Several months ago there were reports that the couple, who met on the set of the 2007 sci-fi flick "Jumper," was taking a break.
The distance between the two actors was cited as a major reason for their split. Bilson is based in Los Angeles and Christensen resides in Canada.
Christensen will appears in the upcoming crime drama, "Takers," with rapper T.I. and Matt Dillon.
