Lady Gaga triumphed in the Best Female, Best Song and Best Video categories, as well as Biggest Fan - a brand new award that celebrates artists with the most committed fanbase.

More than 8,000 fans watched the drama unfold at Belfast's Odyssey Arena, as the world's biggest artists delivered spine-tingling live performances including Justin Bieber, David Guetta, Lady Gaga, Bruno Mars, Coldplay, Red Hot Chili Peppers, Jessie J, LMFAO, Snow Patrol and Queen.

Brit rockers Coldplay opened the awards with an electrifying, amped up performance of 'Every Teardrop Is A Waterfall', while Lady Gaga's sublime vocals for 'Marry The Night', performed against a giant moon sculpture, brought the audience to fever pitch. Global pop phenomenon Justin Bieber got everyone dancing after 'Under the Mistletoe' built up to 'Never Say Never' . DJ David Guetta set the Odyssey Arena alight with his spectacular dance medley featuring Ludacris, Taio Cruz and Jessie J, illuminated by a dazzling array of lasers and glitter balls.

In a more reflective moment, Jessie J presented a moving salute to the late Amy Winehouse in the form of a touching video tribute from the singer's devastated fans.

In a first for the MTV EMA, two outside broadcasts were built into the show, with local heroes Snow Patrol rocking more than 15,000 fans at a spectacular outdoor stage built directly in front of the historic City Hall while over at the historic Ulster Hall, 1200 very lucky Red Hot Chili Peppers fans were treated to a rare, intimate performance by the incredibly dynamic stadium rockers.

Rock legends Queen, who were handed the Global Icon award from Katy Perry, closed the show with a triumphant flourish, lifting the roof with a stunning medley of hits from their extraordinary musical career. Queen veterans Brian May and Roger Taylor were joined by flamboyant US Idols star Adam Lambert on vocals for a musical voyage through their greatest hits including 'The Show Must Go On' , 'We Will Rock You' and 'We Are The Champions' .

EMA host Selena Gomez charmed the audience and showed her comedic flair in a high octane performance that saw her host the main show and the digital show simultaneously. Set piece skits and stunts added to the fun, as Gomez interacted with her own video alter ego on giant screens and mimicked Lady Gaga's famously outrageous dress sense. The 'Monte Carlo' star also took time off from hosting duties to surprise her fans with a sparkling rendition of her hit track 'Hit the Lights' , performed with her band, The Scene.
