12. Steve Kerr / Neil Patrick Harris
Steve Kerr, the legendary Chicago Bull. Although hes aged a bit since he was in his prime, there can be no doubt about who is celebrity doppelganger is. That would be, of course, Neil Patrick Harris, who rose to fame as a child star and hasnt stopped finding work ever since. We think that its too bad he wont be returning to host the Oscars next year, as he was one of the better hosts in recent memory.
