Nickelback won big on their home turf at last night's MuchMusic Video Awards, taking home three prizes at the Canadian music network's annual ceremony. The Jonas Brothers hosted and pulled double duty as performers, taking the stage for "Burnin' Up" and "Paranoid." The Black Eyed Peas delivered a high energy "Boom Boom Pow" and Kelly Clarkson and Rise Against also rocked out onstage, but it was Lady Gaga that had tongues wagging with her "Love Game"/"Poker Face" medley that ended in the recent RS cover star sporting a Madonna-esque cone bra that burst into flames. Gaga also walked away with the International Artist of the Year trophy, while BEP were named International Group of the Year and Jonas Brothers picked up the fan-voted UR Fave International Video award for "Burnin' Up." The night ended on a controversial note as Perez Hilton, who appeared at the show, tweeted that he was assaulted by the Peas' Will.i.am and two security guards.
