Boardwalk Empire's Bobby Cannavale may have won the Primetime Emmy Award for Outstanding Supporting Actor in a Drama Series, but it was his girlfriend Rose Byrne who was the true winner. After all, the I Give It a Year actress was hailed "the love of my life" during Cannavale's acceptance speech.
The Calvin Klein Collection-clad stars celebrated Cannavale's win at HBO's official afterparty, where they were seen chatting up Boardwalk Empire star Chris Caldovino. Other stars at the soiree included fellow Emmy winners Jeff Daniels and Julia Louis-Dreyfus, as well as nominees Emilia Clarke, Michelle Dockery, Kerry Washington, Jane Fonda, Sofia Vergara, Eric Stonestreet and Lena Dunham.
