So much for brotherly love in the City of Brotherly Love! During Friday night’s concert in Philadelphia, newly single heartthrob Joe Jonas attempted to win over the crowd by showing off his drum skills. Sadly, though, instead of hitting a snare drum, he cruelly walloped his baby brother’s hand with a drumstick, sending the show into a temporary delay while stagehands secured a Band-Aid for Joe’s boo-boo. The video is horrifying, but the good news is that everyone survived. [Idolator]
