The Channel 4 show's writer Robert Popper revealed the news when he received a message from the new father on Twitter, The Mirror reports.
"My wife and I sat down to watch Friday Night Dinner and laughed so much her waters broke right afterwards," the message said. "He's a little cracker. Thanks for your help getting the whole thing started."
The writer quipped: "I was so shocked I almost went into labour myself."
Channel 4 recently ordered a second series of the sitcom, which centres on two young men - played by Simon Bird and Tom Rosenthal - who return home every Friday night to see their parents Jackie (Tamsin Greig) and Martin (Paul Ritter).
The first series of Friday Night Dinner concludes tonight at 10pm on Channel 4.
