LONDON -- The MTV Europe Music Awards turned into a celebration of Justin Bieber and Lady Gaga on Sunday night as the two picked up a number of top prizes, including best male and best female act.
Gaga, striking in several outfits throughout the evening, also won for best song and best video for "Born This Way." Bieber picked up best pop act, as well.
Their live performances captured the differences between the two ascendant mega-stars: the teenage Bieber, wholesome and almost impossibly cute; Gaga challenging and aggressively sexual in her approach.
Other awards went to Bruno Mars, Eminem and Katy Perry while the band Queen received the Global Icon award, in effect a lifetime achievement award to the now-graying rockers, who closed the show with a spirited set of their classics, including "We Will Rock You" and "We Are the Champions."
It was a rousing end to the awards show, a highlight on the European music calendar that also draws A-list stars from the United States. It was held in Belfast, Northern Ireland, for the first time.
Queen guitarist Brian May said the show focused attention on how Belfast had found "true peace" after years of sectarian violence.
"It's wonderful to be in Belfast," he said.
The show also included a video tribute to the late Amy Winehouse, who died earlier this year in London.
But the evening was dominated by Bieber and Gaga, the two crowd favorites.
The casually dressed Bieber said modestly that he had voted for competitor Kanye West and thanked his fans and family for his first award.
"Never say never, right?" he said, waving his trophy in the air.
