Global superstars One Direction will tease their forthcoming first movie, the 3D ‘This Is Us’, with the eagerly awaited release of their brand new single ‘Best Song Ever.’ The first song to be taken from their forthcoming third album due for release later this year. On ‘Best Song Ever’ Niall, Louis, Harry, Liam and Zayn deliver yet another memorable modern-pop classic. Fans can get their first taste of ‘Best Song Ever’ when the new trailer for ‘This Is Us’ launched on their official Vevo channel.

The band also have just announced the first two legs of a worldwide stadium tour for 2014 – including eight sold out dates in the UK and Ireland.
