It's safe to say One Direction has another huge hit on their hands!
After teasing fans all week long with snippets of a new single, the boys finally released the full and complete version of "Best Song Ever" early this morning.
There's no doubt Zayn Malik, Harry Styles, Liam Payne, Louis Tomlinson and Niall Horan will be getting the fans singing along with the song's catchy lyrics and chorus. The guys sing: "And we danced all night to the best song ever / We knew every line now I can't remember /How it goes but I know that I won't forget her / Cause we danced all night to the best song ever."
Yeah, it's already stuck in our heads, too.
