Photos of Reese Witherspoon and Paul Rudd Filming How Do You Know in Philadelphia

Reese Logs Another Late Night on Set

Reese Witherspoon was back in Philadelphia last night to film How Do You Know? with Paul Rudd. She's been hard at work on the movie for the past few months, though occasionally Jake Gyllenhaal has been around to provide some handsome distraction. Reese was able to take a few weeks off to chill in LA with her kids Ava and Deacon, who are currently being taken care of by their dad Ryan as they ease back into their school-day routine.
