Steve Martin's a new dad

Will he be a wild and crazy dad?

Who knows? But Steve Martin, 67, is definitely a new, first-time dad.

Page Six reports that the comedian/actor/musician and his wife, Anne Stringfield, 41, welcomed a child in December and have been spotted near their L.A. home with the bundle of joy.

"They've had a baby, and how they kept it a secret nobody knows," a source said. "Steve's very private."

Their rep has confirmed the happy news to Paste BN, so congrats to the new parents!

The couple married in 2007 at Martin's home in a surprise ceremony where guests, including Tom Hanks and Diane Keaton, were told it was a party.
