Royal butler, Grant Harrold, shared a memory of when Kate was ignored at Prince William's 60th birthday party.

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

They dated for around 10 years before getting married in 2011.

They have three children: George, Charlotte, and Louis.

Since the death of Queen Elizabeth II, William and Kate have been appointed the Prince and Princess of Wales.

The couple also keep their Cambridge titles and inherit the Cornwall titles from Charles and Camilla.

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

The royal butler said William and Kate "no different to any other couple that were beginning off, in love and spending time together".

The butler felt "privileged and honored" to be around the couple, whom he described as "brilliant" and "great fun".
