And they may soon be on the road again...
After managing to whip up a storm in the States without even releasing a single there, the boys are back in town.
Though they will be flying back to the US soon to support Big Time Rush, it seems the band's recent UK tour won't be their last.
In a video diary, One Direction have revealed that they may announce another UK tour. What's more Niall took the time to thank fans for their support.
"Thank you for all of your support and thank you all for coming to the tour and those of you that didn't get to come – maybe we'll do a tour next year and you'll get to come along," he explains.
Having spent time sunning themselves in LA, the boys were pleased to be home sweet home. Taking to his Twitter account, Liam Payne was the first to announce the boy band's arrival.
He tweeted: " Woohooo we are home :) xxx," before Harry Styles added: "Touch down!!! Back home :)."
