The Queen has had a major influence on Prince Harry over his lifetime, as the monarch has known him for all of his 39 years. Harry's respect for his grandmother is so strong, he even named his daughter Lilibet Diana in honour of her family nickname. Here are six of the sweetest pictures of the Queen and Prince Harry over the years.

       Perhaps one of the sweetest pictures of Prince Harry and the Queen is one from 1987, when the royals visited the Guards Polo Club in Windsor.

       In the picture, a young Prince Harry is almost three years old and is watching the competition with his grandma.

       For added adorableness, four-year-old Prince William is also present in the snap.

       Members of the Royal Family emerge on the Buckingham Palace balcony every year for Trooping the Colour, the Queen's annual birthday celebrations in London.

       While the day often results in some sweet pictures of the Royal Family, the 2003 event saw a particularly lovely moment between the Queen and her grandsons captured on camera.

       The Queen, Prince William and Prince Harry are all wearing some blue for the occasion and can be seen smiling and laughing with each other during the event.

       Prince Charles married Camilla, Duchess of Cornwall in April 2005.

       Several members of the Royal Family were present for much of the event, including Charles' son Harry and the Queen.

       In one fantastic snap, Harry is seen making a face as he shares a joke with his laughing grandmother.

       While inspecting the soldiers at the passing-out Sovereign's Parade, Prince Harry was part of the event as he was training at the academy at the time.

       In this lovely picture, the Queen can be seen beaming at her grandson, while Harry tries to remain serious but seemingly fails to stifle his smile.

       The RHS Chelsea Flower Show is known to be a highlight of the Queen's calendar every year.

       And in 2015, the Queen was joined by her beloved grandson Prince Harry for the event.

       In one cute picture, Harry is seen giving his grandmother a peck on the cheek before they toured the show together.

       Lady Gabriella Windsor married Thomas Kingston at St George's Chapel Windsor in May 2019.
