One Direction took home 3 prizes, including the Best British Single for "One Thing" (which they played at the ceremony), Best British Album, and Best British Music Act.

The guys had some really sweet things to say for their Directioners when they received the award:

"Guys, this is absolutely amazing. We have to start off by thanking our amazing fans. It's been an unbelievable two years for us. This award's for you."
