Sorry I don't like your edit, you tried to make her look even skinnier, with a smaller nose, different eye color,I don't appreciate photoshop to change people.
Gagas wigs are fine but her natural hair is gorgeous. That dark brown is the same shade as good dark chocolate, very sexy. Gaga is in great shape too. Not thin and wan (Born This Way video for too thin) but very healthy looking. I know how hard Gaga works to stay in shape. I really appreciate the results.
