Cypress is the couple's second child. They have a 2-year-old daughter, Sage Lavinia, and Jack says she is already shaping up to be a great big sister.
"She's really sweet and she was giving him kisses this morning," the 33-year-old actor told us. "It was a lovely thing."
While little Sage won’t be able to watch daddy's new movie -- a retelling of the classic Pride and Prejudice, but this time the Bennet sisters slay the undead -- Jack is all about the girl power in it.
"We need more of it. We really do," he said. "You watch this movie and you watch what they do and you go, 'I enjoyed that more than if it was five guys doing the same thing.' It was cool. It was sexy. It was feminism to the brim.”
