For Uzo Aduba, her first Emmy win truly is a dream come true. "I feel so full of joy. My cup runneth over," the Orange Is the New Black actress gushed to Us Weekly after taking home the Netflix show's first Emmy, for her role as Suzanne "Crazy Eyes" Warren, at the Aug. 16 Creative Arts Emmy Awards. "Mission accomplished."

Presented with a trophy for Outstanding Guest Actress in a Comedy, Aduba beat out five women, including her OITNB costars, Laverne Cox and Natasha Lyonne.

Adding to her Emmy joy: The actress, 33, was able to celebrate her win with her mother, whom she thanked in her emotional speech.

"My mother sacrificed so much . . . for her five children to have a chance. She named me Uza Amaka, which means 'the road is good.' The road indeed was a good one despite its challenges," she told Us after her win.

The mother-daughter duo was able to bond over the experience during a pre-show dance party, Aduba explained. "Pharrell's 'Happy' came on, and that always puts me in a great place. I was playing Iggy Azaela's 'Fancy.' My mom was dancing across the room, just getting excited," Aduba said.
