Happy birthday, Dianna Agron! The actress, best known for her role as Quinn Fabray on Glee, turns 28 today. Although the actress has conquered the TV realm, appearing on shows like Veronica Mars, Heroes, and CSI: NY, Agron has also given the big screen a shot. Last year, she starred in The Family, opposite Hollywood heavyweights, Robert De Niro and Michelle Pfeiffer. Not too shabby! Agron’s standout beauty looks are also something to admire. From her elegant chignon to her out-of-this-world amazing teal eye makeup, the actress has shown that she’s a master of many styles.
