One Direction had a "pretty intense" time on the road in recent weeks.

The British boy band - comprising of Niall Horan, Louis Tomlinson, Harry Styles, Zayn Malik and Liam Payne have just wrapped up promotional tours in the US, Australia and New Zealand for their hit album Up All Night.

Singer Harry is quite exhausted from the heavy traveling and is happy to be back in the UK.

"I'm so tired it was pretty intense but a lot of fun," Harry said on BBC Radio 1 Thursday. "I have six weeks to chill out now."

Harry really enjoyed himself while touring the world.

"My favourite places were New York and Sydney I'd never been to Australia or New Zealand before, so that was sick," he gushed.

Harry arrived back in the UK Tuesday night and hasn't been up to anything extraordinary since his return.

"I went and picked my sister up from the train station today," he shared. "And I'm going to pick up my friend from college because he's got a broken leg."

The band's international tour will commence at London's O2 Arena in February 2013.

One Direction's first American performance will be held in Ft. Lauderdale, Florida June 13 2013.
