Sue and Noel Radford are Britain's version of America's Duggar family and with 21 children already, they have just announced baby number 22. They will now exceed their US counterparts by three offspring.
Sue, 44, and Noel, 48, - stars of the show 21 Kids and Counting which last aired in January - shared their happy news on YouTube, which took viewers along to the ultrasound scan which showed the foetus moving around. The baby is due in April 2020.
"So now you know guys - we're having a baby," said Sue.
"We're just coming up to 15 weeks pregnant and we'll be able to find out the gender of the baby soon."
Proving that no matter how many times a baby comes along it is just as magical as the first, Sue is heard sighing with happiness, saying, "Oh look at the little nose and mouth!"
"I wonder if it will be 11 of each?" said Sue, who has 11 girls and 10 boys.
"I think boy," says the delighted mum. "I'm getting a boy feeling."
Sue gave birth to daughter Bonnie Raye in November 2018 after a 12 minute labour, and despite saying she would be their last, it looks like the couple had a change of heart.
The family lives in Lancashire and still have 19 of their existing 21 children living in their 10-bedroom house, which was formerly a care home. Chris, 30, and Sophie, 25, - the couple's eldest children, have moved out.
Their other children are Chloe, 24, Jack, 22, Daniel, 20, Luke, 19, Millie, 18, Katie, 16, James, 16, Ellie, 14, Aimee, 13, Josh, 12, Max, 10, Tillie, nine, Oscar, eight, Casper, seven, Hallie, four, Phoebe, three, Archie, two, Bonnie, 11 months.
Another baby, Alfie, was stillborn in 2014 at 23 weeks gestation.
Noel and Sue met when they were seven-years-old and Sue gave birth to their first child Chris when she was just 14 in 1989. They not only have their own extensive brood, but are also grandparents four times over.
Noel had a vasectomy when Sue was pregnant with their ninth child, but reversed it when the pair decided they wanted more children.
Sue told the Daily Mail last year that the family finds it hard to afford regular entertainment that other families regularly enjoy. Going to the movies is just one example.
"We do like to go to the cinema, especially in the holidays when the kids are a bit bored, it's raining and there's not much else for them to do. But it can be up to £10 [$19] per person so it can work out really expensive," she said.
Proving that the best things in life are free, Sue said they find joy in the simple things.
"A lot of our best days out have been packing up a picnic and just going for a walk with the kids, or going to a park, or to the beach – and they're all free days out."
They support their large family through their successful bakery - the Radford Pie Company - in their town of Morecambe.
The family does three huge loads of washing per day in an 18kg washing machine and spends three hours tidying every night to keep the house under control.
