Justin Bieber and Selena Gomez stayed close as they walked through a mall in Philadelphia yesterday. The couple stopped by Smoothie King to pick up a cool drink, and they caused quite a crowd as fans gathered to catch a glimpse of the stars. Selena traveled to Pennsylvania to promote her Dream Out Loud Fall collection, which she showed off during an appearance at Kmart earlier that morning. Justin and Selena should return to LA soon since they are reportedly some of the famous guests invited to Kim Kardashian's wedding. The big event takes place today, though even if the duo doesn't make it to the nuptials, they'll be back on the West Coast next weekend for the MTV VMAs where Justin is nominated and Selena will be hosting the preshow.
