The middle Jonas takes his drumming too far and hurts his little brother!

The lovely Jonas Brothers were touring in Philadelphia when things took a turn for the worse on stage!

Woah - looks like Joe really smashed down on Nick's hand when he went to have a go on the drums with his brother. Nick doesn't look very happy about it and declines Joe's offer to hurt him back! Check out the fan made video here:

Oops! It's a good job that big brother Kevin was there to fill in until the next song started!

Are you still loving the Jonas Brothers? Will you be going to see them when they are in the UK in October/November time?

Comments please!
