Is it just me, or is Sienna channeling a tiny bit of Rachel McAdams cuteness in these photos of her on the set of The Best Time of Our Lives? Maybe it's just the slightly Notebook-esque hair.* While it's still weird to see Sienna as a non-blonde, it's honestly refreshing to see her having so much fun on set, even all bundled up. With Keira about to step into serious gear promoting Pirates of the Caribbean: At World's End, I think we'll be seeing a lot of solo Sienna on set. She must be sad to be losing her buddy for a bit.
*Okay, maybe I just miss The Notebook.
