Glee's Lea Michele and Dianna Agron may play high school students on TV, but on the red carpet at Sunday's 2010 Primetime Emmy Awards, it's clear that in real life the two actresses are all grown up--and they've got the glamorous gowns to prove it! Lea looked stunning in a dramatic, ruffled strapless gown and some serious jewelry. Dianna kept it sweet--but no less stunning--in a black and white lace gown with simple accessories.
