Selena Gomez went short and sweet in Giambattista Valli on the red carpet at this evening's MTV Movie Awards. She was solo to pose for photos despite a solid few weeks sticking close to the side of her boyfriend, Justin Bieber. Selena and Justin were on vacation in Hawaii before heading to his native Canada, but they're back in California now so she could guest host Ryan Seacrest's radio show and attend today's big show. Justin is also expected to show up tonight and take the stage, so stay tuned to see if he and Selena repeat their Billboard Music Awards routine with a public kiss!
