Jepsen took home the show's biggest haul with three awards (Video of the Year, UR Fave Video of the Year, and MuchMusic.com's Most Streamed Video of the Year), but it was Bieber who won the most ear-splitting shrieks from the crowd.
The 18-year-old whipped the audience into a frenzy when he arrived on the red carpet holding his baby brother, Jaxon. The screams for Bieber kept coming, from when he won the first award of the evening until the very end of the show, which closed with his performance of "All Around the World."
The show also featured performances from hosts LMFAO, Jepson, Marianas Trench, Flo Rida, Nelly Furtado, Kelly Clarkson and Ed Sheeran.
Marianas Trench and Katy Perry were both double winners, while Drake, The Sheepdogs, Down with Webster and Danny Fernandes also took home hardware.
