Kate was once ignored at Prince William's birthday party, says royal butler Grant Harrold.

William and Kate met at St Andrews University in 2001 and married in 2011 after around 10 years of dating.

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

William and Kate are now the Prince and Princess of Wales following Queen Elizabeth II's death.

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

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

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

He felt "privileged and honored" to be around the "brilliant" and "great fun" couple.

The couple's relationship has blossomed from university sweethearts to a highly visible and loved royal couple.
