Steve Martin becoming a first-time dad at the age of 67!

I had a dream last night that I unexpectedly got pregnant, and had triplets. Two boys and a girl. I remember being quite terrified about having not one but three more kids, and what I would do – at my age. Now, I’m only 35, mind you, but I often am so thankful that I had my children earlier on, so I had the stamina to deal with the sleepless nights. I think if I had to deal with sleepless nights and all the stress of a newborn at 35 – I might go crazy. I realize I had my children VERY young (I was 23 & 25), and I know women have children much later in life these days. More power to them. In fact, they may be on to something. I think if I would have had my kids in my 30′s I may have been more emotionally prepared for the kind of sacrifice it is to have children. Anyway – all this – and my point was…. can you imagine having your first kid at 67!? Steve Martin is 10 years older than MY DAD – and I can’t begin to fathom him having a child at this age.

Thank God for nannies, I guess.

Anyway - Steve Martin IS a new dad, because his 41-year-old wife has already given birth to their first child.

Steve Martin’s become a first-time dad at 67, Page Six has exclusively learned. The “It’s Complicated” star and his wife, Anne Stringfield, 41, welcomed a child in December and have been spotted nearby their LA 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.”

The source added, “They are thrilled. They worked hard to have the baby.”

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.

Martin, meanwhile, has written of his own dad: “My father’s attitude toward my show-business accomplishments was critical. After my first appearance on ‘Saturday Night Live’ . . . he wrote a bad review of me in the newsletter of the Newport Board of Realtors where he was president.”

But Martin wrote in 2008, years after his father died, “In his death, my father . . . did something he could not do in life. He brought our family together.” A rep for Martin declined to comment.

Congrats to the couple….
