But Prince William is “nothing but supportive” of his in-laws, Carole and Michael, with Page Six reports revealing Catherine is intent on growing the company and are talking to investors.
A source told Page Six Prince William is actually very supportive of his wife’s parents, saying: “He’s always admired that they are self-made.”
Three employees were made redundant by Carole Middleton — who has credited children Kate, Pippa and James for its “success”, reported The Sun.
A fourth worker was told their job was on the line.
One shocked insider told The Sun this week: “There is a terrible air of doom and gloom about the place.”
The business, whose slogan is “magical parties for over 30 years”, was set up in 1987 by Ms Middleton, 64, and hubby Michael, 69.
It has struggled recently, and last year Ms Middleton broke a 15-year media blackout to give an interview about Party Pieces which was viewed as a bid to drum up much-needed interest and potential investors.

She had earlier declined numerous media requests in an apparent bid to maintain the privacy of her royal daughter Kate, 37, son-in-law Prince William, 36, and their young family.
Given the chop yesterday were the company’s web designer, PR agent and search engine optimisation wizard.
Another employee — in charge of social media — was told their job is under threat.
Insiders told how in recent months, rather than stocking the warehouse and posting out goods on demand, products are only ordered in as required.
In addition to the latest job losses, three warehouse workers were axed just before Christmas.
But weeks later, when orders briefly picked up, agency staff had to be recruited to replace them.
An insider said: “Despite it being a party company, there wasn’t so much as a Christmas tree or festive decorations in the office. Morale is at rock bottom.”
The idea for Party Pieces came from Ms Middleton’s personal need for supplies for her own children’s parties.
On the company website Ms Middleton is pictured and talks about her children in a message to customers.
She says: “It’s always been a family business and all the children have played a part.
“James established our personalised photo cakes, Catherine started the 1st birthday side of the business, and Pippa developed the Party Pieces blog.”
The Sun reported last month how Party Pieces was slammed for flogging “complete tat” by furious customers.
In her magazine interview last year, Ms Middleton told how her children gave her advice on her party business.
She said: “Because they all grew up with me working, Party Pieces has been very much part of our lives and what we talked about. I still ask their advice and say ‘What do you think of this?’”
It’s not the only Middleton business to be suffering. James Middleton’s personalised greeting card firm Boomf recorded losses of £3 million between 2015 and 2018.
Last night a spokesperson for Party Pieces told The Sun: “Party Pieces owes a duty of confidentially to its employees and cannot comment on speculation.
“We can confirm the business is currently working on an exciting development partnership and long term growth strategy, and as part of this process the company’s structure is being reviewed to align with its financial targets, in consultation with its staff.”
