Already a SAG and Golden Globe winner for her role as Alicia Florrick, the wife of a disgraced politician who rejoins the workforce to support her kids, Margulies lost the Emmy in 2010 to Kyra Sedgwick.
This year, Margulies beat Kathy Bates, Mariska Hargitay, Connie Britton, Mireille Enos and Elisabeth Moss for the trophy.
This was Margulies' second Emmy win out of a total of eight nominations. She won for her role on 'ER' in 1994.
Her Emmy win wasn't the only reason Margulies is making headlines -- just take a look at that dress.
'The Good Wife' returns to CBS on Sun., Sept. 25, 10PM ET.
