Rachel Bilson and Hayden Christensen are great at being a couple, both in real life and on-screen.  After recently staring together in Jumper, they will now be co-stars again in New York I Love You.  We spotted the two on set yesterday, with Rachel sporting a bleach blonde bob and Hayden brushing up on his b-ball skills.

        

REAL LOW.  We spotted Hayden Christensen at a gas station in Los Angeles yesterday with his pants both unzipped and unbuttoned!  I'm not exactly sure how you to manage to do both-as your pants would probably fall off- but the Haydster was definitely getting some ventilation in the crotch area.  Is this how the kids wear their pants these days?  Or did he have a total mental lapse after using the bathroom?  Guesses?
