Not because she is a celebrity OR is married to a very cute celebrity. She's cool because she does not give a shit what her hair looks like! At the "There Will Be Blood" premiere last night, Gyllenhaal was wearing a totally sleek black dress with gold heel ankle boots but looked as if she forgot to do her hair. It was awesome!!! It's a look I try to rock often, because my hair is the worst to tame. What other celebs do the disheveled hair thing? Mary-Kate Olsen, Sarah Jessica Parker (circa 2001) and sometimes Nicole Richie.
