Dennis Ealam, who is 77 and has a total of eight children, 16 grandchildren and three great-grandchildren, is celebrating the birth of baby Violet - but vows she will be his LAST baby.
Dennis and his 37-year-old wife Cora already have toddler Johnathon, nearly three, and baby Jessie, 17 months.
Dennis said: "I love being a dad and am thrilled to bits but I'm too old for any more."
Dennis 'fessed up that his first thought had been 'Oh my God, not another one!' when Cora told him she was pregnant again.
Cora said the pregnancy also came as a surprise to her: "I was on the Pill so it was a massive shock to get pregnant again. But these things happen. It will be difficult but we wouldn't change a thing.
"Dennis and I have a good sex life. People say, 'How does he do it?' But lots of men his age father babies now."
The couple have been together since 2007. Dennis's first wife, Ros, 69, with whom he had five children, is said to have given the couple's relationship her blessing.
Still, Dennis is young compared to the world's oldest dad at 94.
Good luck Dennis - with three babies under three we reckon you're going to need it!
What do you think about this story? Can you imagine having to cope with three babies at Dennis's age?!
