Steve Martin and his wife have a (nearly) new baby

Steve Martin is a new dad — and also darned good at keeping a secret.

The 67-year-old actor, writer, comic and banjo player welcomed his first child with wife Anne Stringfield, 41, his rep confirmed to People on Wednesday, providing no other details.

But don’t go thinking that the child — gender unknown to the public — is an Aquarius. According to the New York Post’s Page Six, which first broke the news, the wee one was born way back in December.

“They’ve had a baby, and how they kept it a secret nobody knows,” a source told the paper. “Steve’s very private.”

The couple has apparently been spotted out with the child near their L.A. home.

“I played fathers so many times, it’s like being one,” Martin said in a 2003 interview when he was promoting the film “Cheaper by the Dozen,” about a family with 12 kids. “I’ve had children of every age. And like I say, I get to do everything but the dirty work. Their parents have to take them home and deal with all that.”

This time, Steve, the dirty work’s all yours. Enjoy.
