One Direction opened the 2013 Teen Choice Awards with a bang -- and with the 'Best Song Ever.'

Wearing their beachy denim best -- even Zayn Malik wore a Betty Boop jacket -- the boys bounced around the stage for their performance of their hit single, then came right back onstage after singing to accept their loads of awards. And we do mean loads! They took home surfboards for a slew of categories.

One Direction won Choice Music Group and Choice Summer Tour, while 'Little Things' won for Choice Love Song and 'Live While We're Young' nabbed a surfboard for Choice Single by a Group.

"You guys are absolutely incredible, you constantly amaze us," Louis Tomlinson gushed. Liam Payned quipped, "This is our last day in America and you've made it absolutely incredible!"

Though they already took home a ton of awards, there are still more they've got nods for -- including Harry Styles for Best Smile!
