I actually think they are all him, he changed over the years. He did not just have his nose and chin done, I do not believe that for one second. Maybe in 1987 that's all that he had done, but around 2000 he must have done something to his jaw (even though I believe his face was naturally very sculpted) because his chin looked like it was an inch longer than his jaw. His eyes in these photos have changed, which I find odd because I'm fairly sure he didn't have any surgery on those...
One thing that never changed... His BEAUTIFUL smile!
