The Middleton party business sells personalised birthday cakes and all the designs have names advertised on the website. However, the designs only have the names George, James and Archie and not Charlotte and Louis. Mrs Middleton is the grandmother to George, Louis, Charlotte and Arthur but their names are not referenced on the website.
The 64-year-old grandmother worked as a flight attendant when she was younger, but after the birth of James in 1987, she came up with the idea for a mail-order business that sells party supplies.
Several of the cakes have the name ‘George’ written on it sparking speculation her eldest grandchild could have a special place in her heart.
The name of Prince Harry and Meghan Markle’s child, Archie, is also popular on the party website.
One of the cakes reading ‘Happy Birthday George’ has pictures of lions on it which may have been given to the six-year-old prince seeing as his favourite film is Disney’s The Lion King.
In an interview with Good Housekeeping Magazine, Mrs Middleton said: “My children have all worked for the business.
“Catherine started the First Birthday brand – she chose the products and looked after all the imagery and the catalogue production.
“Pippa set up the blog, as we didn’t have one.
“James came up with the idea of personalised cakes and got them off the ground for us.
“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?’”
