One Direction: Radio 1's Big Weekend Concert Pics!

One Direction takes center stage during BBC Radio 1′s Big Weekend concert held at Glasgow Green in Scotland on Saturday 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.

“Any time there is an event or anything, they just surprise us and go above and beyond and it’s amazing that still happens to us and we’re just very, very lucky to have the fans that we have,” Harry recently told The Daily Record about the band’s Scottish fans.

He added, “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.”

FYI: Louis is wearing a Levi’s trucker jacket and Niall is wearing a Levi’s vest.
