Reese Witherspoon stopped to pick up some goodies from Jo Malone yesterday afternoon after working up a sweat on a hike with some friends and doggies in the morning. The newly engaged actress has been getting in lots of outdoor exercise lately as she enjoys a brief break in work. She finished filming This Means War just before the holidays, but now there's a chance she'll be back in Water for Elephants mode to take care of reshoots with her costar, Robert Pattinson. The director announced yesterday that they have some minor tweaks to make, including "a surprise for the end!" Whether Reese and Rob will be featured in those scenes is unclear, but the costars' chemistry is evident in the latest round of stills from the highly anticipated movie. Robert will begin his promotional duties as a presenter at Sunday's Golden Globe Awards and even though Reese isn't on the expected list of attendees, she has a spot in Fab's list of 50 iconic looks of the past shows.
