Selena Gomez arrived at the MTV Video Music Awards in LA tonight. She showed up early to help host the preshow and was dressed in a lacy black number for the event. Selena is back on the West Coast after traveling across the country with her band during their tour. Her boyfriend, Justin Bieber, joined her for one stop in Philadelphia, and he'll be back by her side during the show later tonight.
