Rachel Bilson has split from Hayden Christensen

A source told Us Weekly magazine: "She’s full-time back in L.A. He’s in Toronto. They’ve been on the outs for a couple of months. They are completely, officially done."

The news will come as a shock to fans as Rachel - who already has two-year-old daughter Briar Rose with Hayden - previously revealed she is considering adding to her brood.

She said: "I may have another child, that's still up in the air. I'm having so much fun with the one right now. I want to be happy and content. All the life BS that happens doesn't matter. You want to be happy, you want your kid to be happy and you want everyone in your life to be healthy and happy."

And Rachel feels like she has to consider acting jobs a lot more carefully now she has a little one.

She added: "Its not about travelling, she's already a pro on an airplane. She'll say, 'It's time to put up my tray!' It's the actual time that the work takes that affects my choices now."

Meanwhile, Rachel previously confessed her life is "always about" her daughter now.

She said: "My me time is 'we time' now. It’s always about her. It’s not about lying out and watching a movie anymore. Those days are gone! But I’m happy with the new version."

Rachel and Hayden have been dating since meeting on the set of science fiction movie 'Jumper'.
