The American Hustle star and his wife Sibi have become parents to a baby boy.
Christian, 40, and Sibi are also parents to a nine-year-old daughter called Emmeline.
No further details including a name or specific date of birth have been released and, given how private the actor and his wife are, we're not expecting anything else...
Christian previously told Esquire of his desire to keep his family life private: "I've got incredible pride for my family. I've absolutely fallen into that cliché of a dad who could just happily talk about my daughter endlessly. But it's not what I'm about in terms of being an actor. I don't want people to know about that."
He added that it would mess up his job if people knew too much about his private life.
"If you know something about somebody, it gets in the way of just watching the guy as the character."
