Transgender actress Laverne Cox made history on Thursday by becoming the first openly transgender person to earn an Emmy nomination.

Cox, who plays transgender prisoner Sophia Burset in the Netflix series "Orange Is The New Black," will compete for the Outstanding Guest Actress in a Comedy Series award against co-stars Uzo Aduba and Natasha Lyonee as well as Joan Cusack (Shameless) and Melissa McCarthy (Saturday Night Live).

The popular series earned a total of 12 nominations, including nominations for Taylor Schilling (Best Actress) and Kate Mulgrew (Best Supporting Actress).

Cox is thrilled with the nomination, telling the Hollywood Reporter: "I'm on cloud nine. I'm through the roof. We're definitely part of a (cultural) moment.
