One Direction Radio 1 Weekend Pic Special!

One Direction took center stage during Radio 1′s Big Weekend concert held at Glasgow Green in Scotland yesterday afternoon (May 24).

The guys — Harry Styles, Niall Horan, Zayn Malik, Liam Payne, and Louis Tomlinson — played alongside Pharrell Williams, Katy B, Ed Sheeran and Lorde to kick off the annual event.

“There’s just no way to kind of comprehend it,” Harry recently told The Daily Record about the band’s Scottish fans. “You never imagine that anything gets to this level and we’re just so happy and so, so grateful for everything. The fans have made it all happen and it’s insane.”
