Kristen Stewart was flanked by friends for a pizza stop in Woodland Hills, CA, on Monday. She sported shorts and glasses for the outing, which included a stop at Whole Foods, and held onto a can of soda, while her pal carried a bouquet of flowers. Kristen is hanging close to home after a low-key April that included a weekend with Robert Pattinson and Katy Perry in Indio, CA, at Coachella and an afternoon of errands with Rob and his dog, Bear. The couple also spent a little time apart, though, when Rob jetted to NYC for a two-night stay in the Big Apple last week. Rob and Kristen reunited shortly after his return, stopping by a convenience store in Los Feliz for a late-night snack run on Sunday. Rob's on the go again now, and reportedly popped up at the Daughter concert at the Bowery Ballroom in NYC last night.
