The proud new parents announced they were expecting their first child back in June, just after celebrating their fourth wedding anniversary, and an insider told Us Weekly at the time, "They talk about having a couple, though they're thrilled with one now. They treated their dog as a good warm-up."

‘The Social Network’ actor and Chambers, the Chief Correspondent for the Human Rights Foundation, spoke about married life during an August 2013 interview with Town & Country magazine.

"When we finally got together, Armie really wanted to get married," Chambers said, who tied the knot with Hammer on May 22, 2010.

"He sat me down and said, 'Look, we don't have to do this. We could just go our own ways, and then one day you'll be 40 and divorced and we'll run into each other, and we'll laugh and go out to dinner and have this same connection, and we'll wonder why we wasted all of that time,” she continued. “Or we could just do it now and enjoy the ride.'"

Congratulations to the happy couple!
