The LP will include their latest hit "Best Song Ever," which recently garnered them a VMA for Song of the Summer and received the most views on VEVO within 24 hours, clocking in at 12.3 million views.

One Direction made their film debut last week with their 3D concert film One Direction: This Is Us. The film covers the guys' dreams of becoming professional singers to their quick rise to superstardom, and of course the fandom from girls worldwide.

In an interview with Glamour earlier this year, 1D admitted that the obsession with them is something they'll never fully understand. Liam Payne said he still tries to remain incognito as much as he can.

"We kind of try to stay under the radar and not tweet where we are," he said. "Yesterday me and Niall went out shopping in Amsterdam. And literally every single shop we went into, they had to close the shop because there were so many people outside. Some girl tried to pull my hair out. It's quite mad."
