is a romantic – but he doesn't like to admit it.
Joining his He's Just Not That Into You
costars Kevin Connolly, Justin Long, and Bradley Cooper for a chat with Extra

, who was born Jan. 6.
"I correspond with my wife that way," he said, laughing. "She's like, 'Get over here. Pick this s--- up! It's time for you to go get our daughter!' "
