Queen Elizabeth has a close relationship to all of her grandchildren, but it seems that one of them is considered to be Her Majesty’s favorite.

An insider recently told The Sun that the monarch’s favorite grandchild is not Prince William and Prince Harry. In a surprising revelation, the insider said that Prince Edward and Sophie, Countess of Wessex’s eldest daughter, Lady Louise, is the Queen’s new favorite.

“The Queen loves the fact that Louise and James relish their time at Balmoral, and she has become particularly close to Louise, who seems to have become her favorite grandchild, closely followed by James,” the source said.

According to the source, the 15-year-old has been spending so much time with Her Majesty. She is also very artistic, and Lady Louise loves playing and bonding with Princess Charlotte. While Prince William and Kate Middleton were in Balmoral with their children, Lady Louise stepped out and took care of them.

“Louise loves drawing and sketching and was very patiently trying to get Charlotte to do pictures of rabbits and deer. Because of her obvious artistic skill, the Queen allowed Louise to look through some of the collection of Queen Victoria’s Highlands sketches which are kept at Balmoral but are rarely dug out these days,” the source said.

Lady Louise reportedly had a blast while vacationing in Balmoral this past summer. The teenager was spotted horse riding, fishing, taking a walk, and going to church with her grandmother. She also accompanied the monarch in a hack in the hills above the castle.

Meanwhile, Her Majesty is also reportedly impressed with Lady Louise’ younger brother, James’ enthusiasm for fly fishing. The activity was enjoyed by the Queen Mother when she was still alive.

“His enthusiasm for fly fishing delighted Her Majesty because it’s a sport beloved of James’s great-granny, the late Queen Mother,” the source said.

Lady Louise and James are expected to return to school this week.
