A leftover discussion from last night's party: As a female celebrity gets more popular, does she also get blonder? Consider Britney's heyday morph from brunette teen into blonde temptress, complete with a yellow snake. Or Claire Danes' red hair transforming, slowly, into white-yellow tresses to match her supposed A-list status. The same "omigosh" observation goes to Emma Watson, Lindsay Lohan, Nicole Kidman, and Beyonce. Models do it too - Agyness Deyn had honey hair when she first exploded, and now she's a tow head. Mariacarla went blonde too, after her Givenchy campaign, and Kate Moss had a blonde phase that's still growing out. Even Kate Winslet, our favorite actress ever, had a strawberry hue in Heavenly Creatures that turned into a soft shade of butter by The Holiday. But Marilyn Monroe is long gone, and sex comes in all colors - so why are starlets still hitting the bleach?
