Is Rachel Bilson hooking up with Hayden Christensen? God, I hope not.She was seen feeding him (gag) in some new stalkarazzi photos.Since Rach broke up with her soul mate, Adam Brody, I was wondering who she could possibly find to fill the Seth Cohen void. And this is what she comes up with? Hayden is such a girlie-man. Hopefully this was just a case of ladies who lunch.
