One Direction just released a new trailer -- and we're pretty sure that Directions are AOK with it. We already knew that 1D's highly anticipated new track titled, 'Best Song Ever' would be hitting the airwaves on Monday, so it's very good news that we're ALSO going to be treated to yet an amazing One Direction music video for the song that same day! That's right guys, the group just released an official movie style trailer for the visual for their brand new track and as usual, the guys look like they are getting as crazy as ever. Some highlights to note --- let us turn our attention to the fact that Niall is outfitted in full costume and make-up and stars as 'Harvey the Studio Exec'?! He even throws out a Will Smith reference towards the end, yelling out QUOTE, 'Will Smith? Tell him I'll call him back!' Absolutely hilarious! The quick clip also shows some of the other guys getting made over so we can't wait to see what else will shock us in this new video --- but seeing as it's starring Harry, Liam, Louis, Zayn, and Niall, we can only imagine what other kind of hilarity will play out. We also hear that there's going to be a full on choreographed dance routine, complete with backup dancers..
