Justin Bieber arrived at last night's MuchMusic Video Awards in Toronto with his young brother, 2-year-old Jaxson Bieber. Accompanying the Bieber boys on the red carpet was Justin's label mate — and fellow Canadian — Carly Rae Jepsen and his girlfriend, Selena Gomez. It proved to be a big night for the young stars. Justin performed and took home two statues, including international video of the year. Carly Rae won three awards, video of the year, favorite video, and most watched video of the year. Katy Perry also posed for photos with seven little girls, all dressed as characters from her old music videos, before the show commenced. She later performed a cocoon-to-butterfly metamorphosis on stage. She apparently hadn't bargained for how revealing her nude bodysuit was, though, and tried to cover up her rear after accepting one of her two prizes.
