Rachel Bilson and Hayden Christensen have officially ended their romance. In June it was reported the pair had decided to spend some time apart to re-evaluate their relationship. A representative for Rachel has now confirmed the couple have gone their separate ways after more than two years together. “Yes, the engagement is off, therefore, so is the wedding,” the spokesperson said yesterday. Rachel and Hayden announced their engagement in February 2009. However, the actress sparked speculation the romance was on the rocks after she appeared without her diamond ring on the red carpet of a Los Angeles event a couple of months ago. They apparently disagreed on where to live. Hayden, 29, who was born and raised in Canada, had already begun construction on a farm house in Uxbridge, Ontario, while Rachel wanted to remain in Los Angeles with her family.
