Grant Harrold, the royal butler, recalled how Kate was ignored at Prince William's birthday party.

William and Kate first met in 2001 at St Andrews University.

Before they were married in 2011, they dated for roughly ten years.

George, Charlotte, and Louis are their three children.

William and Kate have been named Prince and Princess of Wales since the death of Queen Elizabeth II.

They also keep their Cambridge titles and inherit Charles and Camilla's Cornwall titles.

George is now second in line to the throne, with William now first.

In the words of the royal butler, William and Kate are "no different from any other couple that was beginning, in love, and spending time together."

The couple were "brilliant" and "great fun," so the butler felt "privileged and honored" to be around them.
