One Direction swept last night's BBC Radio 1's Teen Awards in London's Wembley Arena, scooping up Best British Music Act, Best British Single ("One Thing") and Best British Album (Up All Night). Anyone surprised? But the real highlight of the night was when the guys performed "What Makes You Beautiful" and "Live While We're Young" -- check the video above to see their high-energy performance and the excited fan response.
Although Justin Bieber couldn't make the event because of his tour, he still managed to give a killer show. Scroll down to watch. The Biebs pre-recorded an acoustic version of "As Long As You Love Me" just for the award ceremony. The acoustic style and intimate performance were new for JB (he even sang Big Sean's rap verse!), but the gentle, smooth sound perfected suited the song.
But Taylor Swift crossed the pond for the award show, where she performed new single "Red" live for the first time. After the show, she tweeted: "That show was like 'EEEEEEEEEEE!!!' @BBCR1 Teen Awards. Wembley Arena. I'm in love with you, London."
