Sue Radford and husband Noel have announced they are expecting their 20th baby later this year.
The couple already have 19 children ranging from 27 years old right down to eight months.
But it looks like they wanted to even out the numbers and expand their brood to 20.
Announcing the happy news on Instagram to their 17.3K followers they shared a picture of a blackboard with the message: “Boys – 10, Girls – 9. And baby makes 20. Arriving Sept 2017.”
Fans immediately rushed to congratulate the 19 Kids and Counting stars and couldn’t quite believe she was having another little tot.
One follower wrote: “Absolutely awesome news!!! Congratulations.”
“Awwww can’t wait, hope there’s another documentary coming in the future” mics3355 said.
Last year the family featured on ITV’s This Morning as presenter Alice Beer visited their home during Christmas.
Talking about feeding 19 children on Christmas Day Noel said: “We’ll have three turkeys, seven-and-a-half kilos of spuds and endless carrots, swedes and broccoli, and of course Yorkshire puddings.”
The busy couple aren’t on benefits and have their very own bakery to provide for their huge family.
Sue and Noel were childhood sweethearts and ended up having their first child when Sue was 14.
The couple said they were only planning to have three children but loved the experience so much they kept going.
And now 19 children and three grandchildren later the family are known as Britain’s biggest family.
