Flashing a smile on one of her rare days off from Water for Elephants, Ms. Witherspoon did what every girl wants to do when she has a free moment to herself: go shopping!

Reese is currently co-starring with Rob Pattinson in the period film about an elephant trainer (Pattinson) who falls in love with a married circus star (Witherspoon.)

The film doesn't come out until next year, but from the little we've seen on set, we just can't wait!
