Needless to say, the onedirectionmusic.com site crashed immediately, as fans looked to get their ears on the new song written by Louis Tomlinson, Liam Payne, John Ryan, Jamie Scott and Julian Bunetta. You can listen to "Fireproof" here if you haven't yet downloaded it.
Liam tweeted: "Our new album is called FOUR! we've been working so hard on this...so glad we can share it with you!!!"
Niall tweeted: "Guys ! Really excited to announce our new album is called FOUR !!"
Four will be released on November 17 and the guys had a special announcement for Directioners on their site:
"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. 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 for 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. Harry, Niall, Louis, Liam and Zayn xxx"
