good question! i am definently a 팬 of the blonde, but i also think its what makes her 인기 with guys (she has a bimbo image with the blokes)!!! plus, i think it just 슈츠 her better!
I like her hair much much much better blonde and I 사랑 it long like she has it in Poker Face. I don't really like her hair short like in paparazzi... That's my opinion. :)
