Dianna Agron is stunning in Carolina Herrera at the 2012 Met Ball held at the Metropolitan Museum of Art on Monday (May 7) in New York City.

The 26-year-old Glee actress also rocked a Carolina Herrera headpiece, Fred Leighton jewels, Sergio Rossi heels, and a Judith Leiber bag.

“Met ball prep is an art walk moment,” Dianna tweeted earlier in the day, along with a sketch rendering of her hairdo!
