Kate Bosworth looked like a ray of sunshine on her way out after lunch at Il Piccolino in LA yesterday. Must have been an especially celebratory lunch, since 21 opened at No. 1 at the box office last weekend. With Leatherheads joining the race this weekend, we'll see who emerges victorious, but in the meantime hopefully Kate is basking in being at the top. If you're loving her little sundress as much as I am, check out Fab to get your hands on the cute outfit.
