Millie Radford has accused her 22 Kids and Counting star parents of making money out of their grandkids.
Millie made a barbed comment towards parents Sue and Noel after they surprised some of the grandkids with a trip to Florida.
The video saw Sue and Noel tell grandchildren Daisy, Ayprill and Leo that they were taking them on holiday. Millie is mum to Ophelia and Chester, who weren't involved.
Millie, 22, reposted the video on her Instagram, and wrote: "Cute? But you've made money from all your grandchildren but choose your favourites...Said my piece, I recall my kids being in the whole 22 Kids and counting - not a single sight viewing of the rest in there.. bare 1 ep."
Noel even dressed up as Mickey Mouse to share the news, with Daisy bursting into happy tears.
Daisy, Ayprill and Leo are the offspring of Sophie, Sue and Noel's oldest child, and her husband Joe.
The Mirror has contacted the Radfords for comment.
Noel and Sue are the head of Britain's biggest family and have been showing fans what it's like in their household for three series now with their Channel 5 series, which documents everything from living in their house, doing their own home improvements, running their business as well as making big Sunday morning breakfasts for them all.
Earlier this month, ahead of filming a fourth series, the couple and their family , who live in Lancaster, issued a statement to fans, thanking them for their support as they take a "well earned break" ahead of the next lot of filming.
They took to social media to share: "We just want to say a huge thank you for all the love and support you’ve shown throughout our series, we truly appreciate each and every comment and message we’ve received so thank you.
"We are currently having a well earned little break from filming before heading into filming series 4 which we are very excited about."
During the most recent series, Noel announced plans to retire from his pie business, with offspring Chloe and Luke both vying to take over.
Sue recently revealed the pressures of running their business in the earlier years and the bankruptcy nearly caused them to divorce.
She said: "You would go to bed thinking about the debt, wake up thinking about the debt, wake up in the night thinking about the debt.
"If anything would have caused us to get a divorce, it was this shop. Looking back now, it was a time where I genuinely thought our marriage would not pull through. We’d get divorced and that would be it. It was absolutely awful."
