One Direction has been forced to reschedule some dates set for their highly-anticipated U.K. arena tour for next year due to scheduling conflicts. But fans of the band fear not ... they have already been taken care of and revealed so you can adjust your plans for what is sure to be a tour to remember -- and you can also pick up on their British English.

The hugely popular tour will see One Direction making stops at some of the biggest arenas the U.K. has to offer, including London's O2 Arena, Manchester's Arena, Liverpool's Echo Arena, Cardiff's Motorpoint Arena and Nottingham's Capital FM Arena.

Only four of the tour's 34 dates had to be adjusted, including the shows originally set for March 24 (Newcastle Metro Arena), March 26 (Sheffield Arena), March 27 (Newcastle Metro Arena) and March 29 (Glasgow SECC).

The adorable blokes are currently on tour in the good old U.S. of A. with their pals Big Time Rush. The band will continue their current tour with the Nickelodeon-assembled pop rockers despite Zayn Malik's abrupt (albeit temporary) exit. The group is slated to perform at the Nickelodeon Kids' Choice Awards, as well as to host the network's Saturday night lineup leading to Big Time Rush's 'Big Time Movie.'

To commemorate the occasion and pay tribute to their friends, One Direction recently covered a Big Time Rush track, as well as dished on British English -- and even wished a certain other pop phenom a happy birthday. Tune in below to hear them sing and explain exactly what "knackered" means!
