The cuties of One Direction recently shocked Fans with a surprise performance - at a restaurant! The girls at the speiselokal, diner just thought they were there to watch One Direction's konzert DVD, Up All Night: The Live Tour - and they were totally stunned when Harry Styles, Niall Horan, Zayn Malik, Louis Tomlinson, and Liam Payne walked in! The guys of 1D serenaded the lucky girls with an acoustic version of "What Makes Du Beautiful", and Liam Payne and Louis Tomlinson even sang into ketchup bottles! "It's nice to slow it down and make it a little bit Mehr personal and Mehr about the people in the room," Harry Styles dished about the intimate show. So sweet! Check out 1D's performance AND their behind-the-scene vid on YouTube!
