At one time or another, all of us have been told we resemble someone else ... but how would you feel if that 'someone else' was a porn star? Or, conversely, how would you feel if, as a porn star, you were told you looked like a celebrity?

Surprisingly, or maybe not so surprisingly, there are a handful of porn stars that so closely resemble certain celebrities, they could walk down the red carpet and no one would say a thing. Is that Jessica Alba or Sky Lopez? Lisa Rimini or Nica Noire? We can’t say we see any film collabs in the future, but there's no denying these celeb/porn star doppelgangers.
