You know what they say, imitation is the sincerest form of flattery. And last year Kim Kardashian (and her sis Kylie) "imitated" many of Naomi Campbell's runway looks from the 90's. But, I guess it's a good thing that they're friends, because if I were Naomi, I would have been a little annoyed. And at the same time, I can't really blame Kim. After all, Naomi is an original supermodel and true fashion icon....who's also celebrating her 50th birthday today!
