Glee's Dianna Agron In Stella McCartney On The Late Show With David Letterman

As out and proud Gleeks, we've long been fans of the gorgeous Dianna Agron - but the actress showed off a new, more sophisticated style side yesterday for an appearance on The Late Show with David Letterman.

And it's a long way from McKinley High...

The 25-year-old showed off her enviable figure in a fitted Stella McCartney LBD with waist peplum, teamed with her new tousled bob and a pop of pink lippie.
