Dianna Agron: 'Glee' Premiere Pretty

Dianna Agron glams up the red carpet at the premiere of Glee: The 3D Concert Movie held at the Regency Village Theater on Saturday (August 6) in Westwood, Calif.

The 25-year-old actress wore a Christian Cota tulip wrap sleeveless dress in a printed textured chiffon, Camilla Skovgaard shoes, a Ferragamo bag, Cathy Waterman earrings and bracelet, and an H Stern ring.

Dianna just returned from promoting the flick in NYC — where she stopped by the Late Show with David Letterman and and Late Night with Jimmy Fallon.
