One Direction have kicked off their 'Take Me Home' world tour.
The five lads took to the stage for two performances at London's O2 Arena on Saturday, marking the start of their eight month jaunt.
Harry, Louis, Liam, Niall and Zayn were greeted by the usual screams from their hordes of fans as they belted their way through their hits, including current Comic Relief single 'One Way Or Another (Teenage Kicks)'.
At one point during the show, the boys were transported across the arena over the heads of fans to perform at a second stage in the centre of the O2.
Niall also proved his musicality by bringing out his guitar to play along to some of the set, which also includes a cover of Wheatus' hit 'Teenage Dirtbag'.
The tour will see the boys play over 100 dates and travel across Europe before heading to the US and Australia, before finishing up in Japan at the beginning of November.
