I can't speak for everyone, but the one thing that has held me back from thinking Megan Fox is a true beauty is because its so obvious that she has had a lot of plastic surgery and uses a lot of make up tricks to look like Angelina. One think that I actually like about Adriana is that unlike Megan she has avoided trying to look like an Angelina clone, which she could very easily if she tried. Also, aside from the hair and eye color, I honestly dont know why people compare her to the likes of women like Adriana and Angelina, Megan is beautiful no doubt, but not on the same level as them.
Also, I have to say I dont get why Adriana people think that every girl with dark hair/light eyes looks exactly like Adriana. Take for instance Emily DiDonato who facially looks much more like Mila J, and Doutzen than Adriana but because they have similar coloring people go on about how much they look alike. To me Adriana looks a lot more like Jessica Alba/Alicia Keys.
