Rachel Bilson and Hayden Christensen split after 10 years!

Say it ain’t so!

We’re sad to report that another one of our favourite A-list couples have called it quits.

Rachel Bilson and Hayden Christensen – who have been in an on/off relationship for almost ten years – are most definitely off again.

And if we are to believe sources, the former O.C actress and Star Wars actor may be off for good.

“They are completely, officially done,” an insider told US Weekly.

So why did they decide to go their separate ways? Apparently distance was largely to blame for the split…

“She’s full-time back in L.A. He’s in Toronto,” one source said.

“They’ve been on the outs for a couple of months.”

Regardless of the reason, the couple do have one daughter together – little Briar Rose, who was born in 2014 – so we hope they will remain amicable for her sake.

And we’re still crossing our fingers that they may reunite one day!
