Princess Charlotte, the 11-month-old daughter of Their Royal Highnesses the Duke & Duchess of Cambridge, was featured sitting on the lap of her paternal grandmother, Her Majesty Queen Elizabeth II of the United Kingdom of Great Britain and Northern Ireland, in an adorable family portrait of the monarch with the youngest members of the British royal family that was released on Wednesday -- the day before she celebrates her 90th birthday. People reports that the portrait was taken by legendary photographer Annie Leibovitz on March 28.

Annie Leibovitz's portrait includes the queen's youngest grandchildren, Prince Edward's children Lady Louise, 12, and James, Viscount Severn, 8. The rest of the children in the portrait, including Princess Charlotte, are the queen's great-grandchildren: Princess Charlotte's older brother, 2-year-old Prince George, and Princess Anne's three grandchildren, Savannah Phillips, 5; Isla Phillips, 4; and Mia Tindall, 2. The Phillips girls are the daughters of Princess Anne's son Peter Phillips, and Mia Tindall is the daughter of Princess Anne's daughter Zara Tindall, who is married to retired rugby player Mike Tindall.

Princess Charlotte, who now has dark hair like her mother, the Duchess of Cambridge (formerly Kate Middleton), is holding a small toy horse in the photo. Mia Tindall is holding the queen's handbag, which she picked up without having been asked to do so, according to an anonymous source who spoke to People.

Princess Charlotte is probably too young to be a public headliner during the 2016 Trooping the Colour ceremony, but Prince George made an appearance last year when his father, who is also known as Prince William, held him as the royal family stood with Queen Elizabeth II to watch the Royal Air Force do a fly-past at the end of the celebration. Prince William also made his first Trooping the Colour appearance at the age of 2, and also in the arms of his father, Charles, the Prince of Wales.
