Dianna Agron has spent much of her acting career playing Quinn Fabray, mean girl and head cheerleader on “Glee.” That meant her hair was usually in a high, blonde ponytail. But when season three premiered, Quinn Fabray suddenly had a pink, choppy bob, complete with rocker bangs. In real life, Agron ditched the pink hue but still kept the rocker look.

It was an extreme departure from Agron’s usual look, but Knudsen thinks she nailed it. “Dianna has the perfect hair to pull off that choppy style. She just looks smokin’ hot and sexy. Obviously, Dianna is beautiful without the bangs, but this just updated her. She looks like a totally different person.”
