Kate Middleton’s parents, Carole and Michael Middleton, are doting grandparents to her children.

According to Lucy Devine and Becky Pemberton of The Sun, Carole and Michael play an “integral role” in Prince George, Princess Charlotte and Prince Louis’ lives. In fact, Carole brings the kids to their family business, Party Pieces, and lets them pretend that they run the company.

“Carole has taken the kids to Party Pieces and they played shopkeeper there with all the stock,“ royal expert Phil Dampier told Fabulous Digital.

“Prince George goes out a lot with his grandmother Carole. They go to the beach there and they are very close.”

Aside from allowing them to play games at their company, Middleton’s parents often treated them with sweets and chips. One visitor even spotted Prince George sitting in front of the house exclaiming “Oh my gosh!” after Carole gave him a bag of sweets for being well-behaved while Middleton and Prince William were away.

One time, Middleton called her mother while she was on tour only to hear Prince George telling her that his granny “gave him chips again” for dinner.

Carole and Michael also joined Prince William, Middleton and the kids during their summer holidays in Mustique last year. The Duke and Duchess of Cambridge were spotted enjoying a rare wild night out at the private island.

Prince William and Middleton blended with the other tourists and were photographed dancing. According to insiders, the couple left their kids at the care of Carole and Michael.

On Monday, Prince George celebrated his 6th birthday. Prince Harry and Meghan Markle greeted him on social media. However, royal fans were furious because the Duke and Duchess of Sussex didn’t address him correctly by not calling him “HRH Prince George” when he is the future king.

In related news, Middleton reportedly got baby Botox. A surgeon shared two photos of Middleton on Instagram alleging that it was the “before” and “after” pictures of the duchess following the procedure. Kensington Palace issued a statement denying the surgeon’s claim saying that it was “categorically not true” and that the royal family never endorses commercial activity.
