Rose Byrne and Bobby Cannavale made their first red carpet appearance as a couple at the CFDA Fashion Awards in NYC last night.
Byrne, 33, has been dating Cannavale, 43, since the fall of 2012. They had not attended a red carpet event together until yesterday.
They had been linked in late 2012, and a source said they had only "been dating for a few months." They then took their relationship public at the Killing Them Softly afterparty on November 26.
Cannavale was previously married to actress/screenwriter Jenny Lumet from 1994 to 2003. They have a son, Jake. Byrne was previously dating writer/director/actor Brendan Cowell and writer/director Gregor Jordan.
Cannavale starred in Broadwalk Empire and Byrne starred in Bridesmaids.
