Princess Kate has long been one of the most beloved members of the royal family, praised for her warm, caring, and dependable nature. A few royal experts have even dubbed her the “Rockstar” of the royal family. This is why it comes as no surprise that she maintains close ties throughout the family, alongside remarkably wholesome relationships with her parents and siblings. However, it turns out that one of her closest confidantes is not really a blood relative. In fact, she has built an unexpectedly close friendship with a key member of the extended royal family, Sophie, the Duchess of Edinburgh.

The Duchess and the Princess share a bond that has been growing for ages, alongside their expanding royal roles. Now, it has evolved into one of the strongest relationships in the Royal family. According to HOLA!, Royal commentators have also often acknowledged their bond by calling Sophie “the older sister that Kate never had.” This is all because of the love, care, unilateral support, and undeniable guidance that the latter seems to have provided for Middleton over the years. Their friendship isn't new; reports suggest it dates back to the time when Middleton initially joined the royal family. However, the mastermind behind this pairing was none other than the late Queen Elizabeth II herself.

Reports suggest that the late Queen was the one who asked Sophie to connect with Middleton, encouraging her to mentor the new Princess on how to navigate everything, including the know-how of royal life as a whole. Having come from a middle-class background herself before marrying Prince Edward, the Duchess deeply understood the unique challenges of adapting to the monarchy, making her empathetic towards Middleton’s troubles. Who knew that this relationship, which started as an informal mentorship, would end up blossoming into a genuine, lifelong friendship?

Another reason Middleton and the Duchess are so close is that their relationship is built entirely on mutual appreciation, complete understanding, shared experiences, and absolute trust in each other. These have become the backbone for their invincible relationship. Their age gap has also turned Sophie into a protective older sister, who loves to go above and beyond to support and defend Middleton. Elaborating on this, the Royal biographer Ingrid Seward told HELLO! that the pair "have a sisterly bond.” She further added, “They are both protective of their children. Sophie has had a young family, so she knows what it's like trying to protect them while being in the royal world.” She also went on to explain how the Duchess has been privately supporting and cheering for Middleton from the background, which is just so wholesome!
