Joe and Bex were live from Barclaycard presents British Summer Time at Hyde Park and ran around chatting to loads of the amazing acts playing the festival.
Joe caught up with Diversity straight after their awesome performance to tens of thousands of people up on The Great Oak Stage.
Elsewhere the line-up was packed with stars, including The Vamps, Lawson, Rixton and Elyar Fox, and was headlined by supergroup McBusted!
