First Rachel Bilson and Hayden Christensen were seen holding hands, now it's super obvious they're together.

Rachel and Hayden (both 25) were spotted spoon feeding each other lunch on Wednesday afternoon in L.A., passing food back and forth.

At the end of their lunch date, Hayden even drove Rachel's car back to her house in L.A.

Rachel and Hayden also went grocery shopping together yesterday too, now that's love.
