Kate Middleton and Prince William shared their secret on how to please Queen Elizabeth II.

In an unearthed interview with the BBC radio back in 2017, the Duke and Duchess of Cambridge gave a glimpse of how they celebrated the monarch’s 91st birthday. The couple was asked whether they bought the Queen a present.

Prince William laughed and admitted that it’s “quite hard“ to give Her Majesty a birthday present because she has got a lot already. Considering her age, Queen Elizabeth II had no shortage of presents in her lifetime, so getting a unique gift is really a challenge.

Middleton revealed that they make homemade gifts and even complimented her husband for being good at this. “You’re very good at making things,” the duchess said.

Prince William agreed and said that they make a few things. Most were handcrafted items and often were creations of their eldest son Prince George whom the second-in-line to the throne said is “very good at arts and crafts.“

“Now with the great grandchildren around, you see they can make stuff. And of course, that goes down really well,” Prince William explained.

“It doesn’t matter what it looks like, it just goes down really well, so we stick to those sorts of presents,” he added.

Prince William isn’t the only royal who struggles when it comes to choosing a present for Queen Elizabeth II. During Queen Elizabeth II’s 92nd birthday, the Duke of Sussex made a joke at the monarch’s expense about finding gifts for her. Meghan Markle’s husband said in his speech that Her Majesty is someone who is not easy to buy gifts for.

Between the two, the Queen is closer to Prince Harry compared to Prince William. According to E! News royal correspondent Melanie Bromley, the Queen and Duke of Sussex has a more “fun” granny-to-grandson relationship because the latter is way down the line of succession. Meanwhile, her relationship with the Duke of Cambridge is “half family and half business.”

Just recently, Prince Harry and Middleton reunited at Anzac Day Service at Westminster Abbey. The netizens were very pleased to see the duo together. Many believe that Middleton and Prince Harry are very fond of each other and have no tension despite the rumors that the Cambridges and Sussexes are having a falling-out.
