MUM-OF-21 Sue Radford, 44-who is pregnant with her 22nd child-is taking her kids to Australia for four weeks.
Britain's biggest family took to their YouTube channel -where they have over 123,000 subscribers-yesterday to reveal they would be taking the month-long holiday when daughter Tillie has a frame removed from her leg.
The nine-year-old had to have an operation and a frame fitted earlier this year to lengthen her right leg after it stopped growing due to a procedure she had at 18 months old.
With Tillie having had a check-up with the doctor to ensure all was well, the family decided to announce their holiday plans.
"We've been wanting to book Tillie's surprise destination holiday but we thought we'd better leave it because we didn't want to book it and then there be some major problem with Tillie's leg and we couldn't cancel the holiday or change the dates, "said dad Noel.
"Today we've been to hospital and it's been brilliant news so we've booked our holiday of a lifetime and Tillie is going to reveal where we're going. None of these lot know!"
The camera then turns to Tillie who reveals the family are set to visit Australia for a month-and the rest of the kids were mega excited.
"The idea is we're gonna fly to Brisbane and then we'll do a road trip down to Sydney, stopping off at different places for a week at a time," continued Noel.
And it looks like the family will also be visiting the Bonells -an Australian family of 18.
"By coincidence today this box arrived from our friends in Australia, the Bonell family who we met three years ago," said Noel.
"They are one of Australia's biggest families, they have 16 children, and we still keep in touch."
The kids can then be seen opening a box of festive treats all the way from Oz.
And the family couldn't contain their excitement over the trip as they made plans to visit a koala sanctuary and Sydney Opera House.
Last week, we told you how mum Sue transformed the kids' bedrooms and gave them a festive makeover for Christmas .
She shared a video surprising the children and kitting out their bedrooms with festive bedding and decorations.
The super-mum lives with husband Noel, 48, and their 21 kids.
The couple famously don't claim any benefits apart from Child Benefit and rely on Noel's bakery business to make ends meet.
