Singer-songwriter Ed Drewett has revealed his anger upon realising that One Direction's forthcoming new single, 'Best Song Ever', has leaked online.

The hitmaker co-wrote the track, which was due to have its first play this Friday, and after it found its way online earlier this afternoon (July 17), he took to his official Twitter page to confess his disappointment about how something he worked so hard on has been released prematurely:

"How has Best Song Ever been leaked?! I was only allowed a link for 24Hours & I co-wrote the bloody song. S**t when people do that. F**k you."

One Direction's Niall Horan recently admitted that 'Best Song Ever' is one of the best songs his group has recorded to date: "Can't wait for you guys to hear BSE! one of my favourite 1D songs for sure!! it’s getting its first play on Friday so hope you like it"
