Was amazing to see them two times in one week; first at the emirates on the monday and then at the summertime ball on saturday! I was singing every single word of theres the whole way through and made sure everyone was aware they were the best act there and tried my best to put all the beliebers to shame haha :P i also loved how even when they had left the stage, they were in a way still there the whole night because those inflatible balls were in the crowd till the very end! :P
