So there has to be a good reason Rachel Bilson, the talented and O.C.-crushworthy actress, was out shopping with a doll.
Because her stuffed tiger was at a tea party?
Because she'd just completed adoption through Toys "R" Us?
Because "It's mine! Mine!"?
We could tell you she's holding it while shopping with her little sister, which is what we think is the case, but we know you would rather try to guess yourself.
So have at it: Tell us why you think she's holding the baby doll.
