Beyonce
Katy Perry
Lady Gaga
Lady Gaga is just plain butt-ugly...I've never heard anyone refer to her as good looking - course, I don't think I've ever had a conversation about her apart from this forum. And Katy Perry, while light years better looking than Gaga, doesn't do anything for me either.
But Beyonce is absolutely beautiful, though she has a little too much meat on her for my tastes.
Lady Gaga is a bit much in her over-the-top garb, dermals and eggs and such, but honestly when she's dressed down she looks ten times better. natural beauty imo.
