In just three hours, 10,000 people grabbed the free passes to the 2009 MTV European Music Awards in Berlin, in honor of the 20th anniversary of the fall of the Berlin Wall. How ironic that the organizers mounted a 12-foot wall at the venue to keep those without tickets from watching the show.

That didn’t stop the musical guests from giving earth-shaking performances. Beyonce Knowles not only bagged the best female artist award and best song award for “Halo,” but also wowed the audience with her racy red outfit as she performed her hit “Sweet Dreams.”

Wall-to-wall would be an understatement for Katy Perry’s costume changes and hosting skills. From her various red carpet frocks to her glittering stage costumes, Perry’s wardrobe did not disappoint fans that night.

Other highlights included performances by Green Day, Tokio Hotel and Leona Lewis. For a complete list of winners and a gallery of red carpet garbs, visit the official MTV Euro site.
