Shawn Mendes treated the #CapitalSTB crowd to a stunning set.

He was one of the most anticipated performers on the line up and Shawn Mendes certainly didn't disappoint when he took to the stage for a stunning set, including a soulful Ed Sheeran mash up. 

The Canadian star has gone from a Vine star to a legit musical superstar - and we saw all the tweets you guys sent us asking for him to be on the line up! Shawn told the crowd, "This is the most insane thing, I've done ever", as he performed for his biggest ever crowd - we like to make dreams come true at the #CapitalSTB!

Shawn brought five of his biggest hits to entertain the crowds - and judging by the screams when he came onto the stage - you guys were SO up for partying with him! He opened with 'There's Nothing Holding' Me Back' and he couldn't wipe the smile off his face to be performing for his UK fans again.

Shawn took the time to surprise a mega fan backstage - talk about the dream scenario... yep, we're jealous! 

Ahead of his turn on the stage, Shawn popped by our backstage tiki bar and played dares... which may have ended up with him having an impromptu haircut! Eek! 

Well, we know you're game for a laugh, Shawn!
