Justin Bieber Fever Sets Toronto on Fire at MMVAs
You didn't even need to turn around to see if Justin Bieber had arrived at the 2010 MuchMusic Video Awards. The million-decibel screams said it all -- the current Boy Wonder had hit the red carpet.

In a swirl of camera flashes and young girls' tears, the pop superstar came and went from the red carpet in a flash. Bieber was unquestionably the big draw of the night, but he had a little help from pop queen Miley Cyrus, who hosted the awards ceremony. Fans held signs reading, "I have Cyrus Virus and Bieber Fever!"
