He starred in Cheaper By the Dozen but Steve Martin has to be happy with just one!

According to the New York Post's Page Six, the actor/comedian and his wife, Anne Stringfield, welcomed a child back in December, and they've been seen near their L.A. home with the baby.

“They’ve had a baby, and how they kept it a secret nobody knows,” a source told Page Six. “Steve’s very private." However, this is definitely a happy occasion for them. "They are thrilled," the source added. "They worked hard to have the baby.”

Steve is 67. Anne is 41. They were married in 2007. A rep for Steve declined to comment to Page Six, and there's no word on the baby's gender or any other details. But it sounds like the "Wild and Crazy Guy" is about to go on a wild and crazy ride as a father. Congrats!
