This has been blown out of reality. It's Halloween and she was being specific with dressing up as Lil' Wayne. Lil' Wayne is a character that is put on for a rap career. I'd be more worried about what message is put out to the young public by Lil' Wayne and other shallow, money worshiping rap artist that continually exploit and degrade women in their videos and shows. I'm a Hip Hop fan of substance.
Are we to get upset when people dress up as American Indians, Chinese Shanghi Poster girls, Guisha girls, Mexican Banditos, French Maids, Don King, Priests and Popes etc.?
Come on, she was dressed as Lil' Wayne. Guarantee this cheerleader has bought, likes and danced to many of his songs. This was not a Black Face outfit. It was a very specific person she was dressed as for Halloween. Complete with her jeans hanging down off her ass.
