One Direction performed at the 2012 Olympics closing ceremony and it was totally awesome! The boys performed one of our fave One Direction songs, "What Makes You Beautiful," on a moving stage! Niall Horan spilled, "Omg that was unbelievable, highlight of our career, and the biggest audience we will ever play to, 1 billion people! #ThankYouLondon2012!" Before One Direction rocked the stage at the closing ceremony, Louis Tomlinson and his girlfriend, Eleanor Calder, went to the Olympics to cheer on English diver Tom Daley! So sweet of them to support their home team!
