Beyonce and Lady Gaga dominate MTV Video Music awards
Beyonce's pregnancy and Lady Gaga's drag act were the talk of this year's MTV Video Music awards, where tributes were paid to the late Amy Winehouse.
Beyonce wordlessly confirmed she was expecting by rubbing her baby bump at the end of an on-stage performance.
The flamboyant Lady Gaga, meanwhile, appeared as her male alter-ego Jo Calderone at the Los Angeles event.
Tributes were paid to late singer Amy Winehouse, while Adele won three prizes for her Rolling in the Deep video.
Yet it was Katy Perry who took home the night's most-coveted trophy, picking up the video of the year award for Firework.
The promo also received a prize for its special effects, with Perry getting another "Moonman" statuette for her collaboration with rapper Kanye West on the video for her song ET (Extra-Terrestrial).
Pop star Britney Spears was honoured with MTV's Vanguard Award and won an additional prize for her Till The World Ends video.
Elsewhere R&B star Chris Brown soared above the crowd during a gravity-defying rendition of his hit Yeah 3X.
As previously announced, veteran crooner Tony Bennett took to the stage to introduce footage of him recording jazz track Body and Soul with Winehouse in March.
"You just can't be a jazz singer - either you've got it or you haven't," said the 85-year-old. "Amy had the whole gift."
US singer-songwriter Bruno Mars also paid homage, ending a cover version of the Winehouse hit Valerie with the words: "Amy, we'll miss you baby."
Lady Gaga ended up with two awards on Sunday, receiving both the female video and "video with a message" prizes for her Born This Way promo.
Foo Fighters, Nicki Minaj and Justin Bieber also collected trophies at the event, held at the Nokia Theatre in Los Angeles.
