Hayden Christensen hit the links yesterday, wearing what can nicely be called exceptionally informal attire. No golf plaid for him! Supposedly Hayden and longtime girlfriend Rachel Bilson broke up earlier this summer, though some reports just say they’re taking a break. In June friends of the couple said they were taking a month off and then would reevaluate, but Bilson and Christensen haven’t been pictured together since then. Hayden doesn’t look like he’s too broken up about it, to say the least.
