Maybe blondes really do have more fun after all. Just two months after debuting a fiery new hair color, Dianna Agron has ditched the red dye job in favor of the lighter, golden-hued locks she used to rock.

The I Am Number Four actress, best known as Quinn Fabray on Glee, showed off her back-to-blonde 'do at a MySpace party on Wednesday, June 12, at the El Rey Theater in L.A. Bright raspberry lipstick and a flirty floral skirt by Marc Jacobs enhanced the summery shade, as did the crisp white blouse and white pumps she wore.

The 27-year-old star is no stranger to experimentation when it comes to the cut and color of her hair. Two years ago, in 2011, she chopped her long tresses into a shaggy bob. And a few months later, she dyed her blonde locks a bright pink color for her role on Glee.

Her most recent change came in April, when she stepped out with a new red 'do and sideswept bangs. (She kept the latter when she went back to blonde.)
