Bradley Cooper's Doppelgänger Causes Mayhem At Sundance Film Festival

Real Bradley Cooper might have been associated with crashing weddings, but fake Bradley Cooper? He prefers Sundance Film Festival afterparties.

Complex reports this mischievous doppelgänger remains unnamed; although, it's 100 percent not Bradley Cooper.
