The Vamps rocker Bradley Simpson was left bleeding during a concert in London over the weekend (05-06Jul14) when he accidentally crashed into his bandmate James Mcvey onstage.

The Brits were among the acts to take to the stage at the Barclaycard British Summer Time Festival in Hyde Park on Sunday (06Jul14), and Simpson's overzealous performance left him with a split lip.

The 18 year old was tended to by medics at the side of the stage before powering on through the set.

After the show, he tweeted: "Hahaha I'm fine I just thought it would be a good idea to run into James' shoulder, then bleed a bit. Well done Brad. Awesome gig though."
