"Hey guys! We're so excited to announce our fourth album, Four! We've worked incredibly hard writing and recording it whilst we've been on the road and we couldn't have done it without your support," the group wrote on the website. "As a special thank you for everything you guys have done for us we wanted to give you 'Fireproof'-it's a track from the album and you can get it free right now. You'll be able to download it for free for the next 24 hours. We hope you enjoy it and we can't wait for you to listen to the album in full. Thank you, you guys mean the world to us."

Billboard describes the band's newly released "Fireproof" single as "an easy-going pop song eschewing the high-energy attack of 'Best Song Ever' or the Mumford-lite vibe of 'Story of My Life' in favor of a gentle (and extremely catchy) melody. To check out 1D's new single, click here.

"I feel like we've blagged it again," he says in the film. "You look at the names of who's played at Wembley and you almost feel like you're not worthy of it. We just feel like we're just little scumbags."
