Prince William, Kate Middleton pay tribute to Queen Elizabeth II on 100th birthday

​Prince William and Kate Middleton are honoring Queen Elizabeth's legacy on what would have been her 100th birthday.

​As April 21 marks the late monarch's centenary, the future king and his wife Kate also poured their love on the special day.

​The royal couple took to their Instagram account and shared a heartfelt note along with a series of snaps with the queen, who passed away on September 8, 2022, at the age of 96.

​They wrote, "Remembering Her Majesty Queen Elizabeth II on the 100th anniversary of her birth. Inspiring generations through a lifetime of duty."

​The first slide of the post featured an old snap of the Queen when she was a princess.

​In the second snap, both Kate and William, as well as Queen Elizabeth, can be seen looking at something outside of the frame.

​While in one of the pictures, the late monarch was photographed interacting with Kate and William's youngest son, Prince Louis.

​As the commemoration of the late Queen's birthday is going on in full swing, King Charles also paid tribute in memory of his "darling Mama."

​The king shared a montage video for the queen and wrote, "God bless you, darling Mama; you remain forever in our hearts and prayers."
