Reese Witherspoon left lunch at P.F. Chang's in LA yesterday wearing her hot Givenchy bag and a cheery red dress — right in tune with Fab's advice for putting together a look inspired by Valentine's Day. Since wrapping her last project, This Means War, Reese has been focused on finding the perfect wedding dress, hanging with family, and fulfilling her Avon brand ambassador responsibilities. She's also been keeping up a rigorous workout routine that includes intense jogs. Reese's fit frame is front and center on latest Water for Elephants poster as is her handsome costar, Robert Pattinson.
