On Thursday night, Emile Hirsch showed up at a Diesel U concert at Webster Hall in New York City to find out that...he'd already arrived with an entourage of eight. The Emile doppelganger had arrived first, and a publicist asked him if he wanted to walk the red carpet, which he kindly refused. But that didn't stop him from taking a whole bunch of comp tickets. I hope the two didn't see each other, cause I hear when parallel beings come into contact, one of them has to be destroyed! [NY Post]
