The 41-year old television actor bagged the award for Best Performance by an Actor in a TV Series Drama for his role in 'Homeland', E! News reported.
After the award-ceremony, Lewis headed straight to a bash thrown by Fox network and performed Gangnam Style moves made famous by the South Korean rapper.
His onscreen son Jackson Pace joined in the routine, before Lewis hit the floor for a slow dance with his wife, Helen McCrory.
The actor refused to talk to the press on his way to the afterparty, and said, "I'm too drunk to talk!"
