Once, at Prince William's birthday party, Kate was completely ignored.

The couple first crossed paths in 2001 at the University of St. Andrews.

After dating for a decade, they finally tied the knot in 2011.

Their names are George, Charlotte, and Louis, and they have three children.

Following Queen Elizabeth II's death, they were named Prince and Princess of Wales.

They receive Cornwall titles from Charles and Camilla and preserve their Cambridge titles.

George is second in line for the throne, and William is first.

Their butler called the couple "excellent" and "wonderful fun."

The butler was "honored and privileged" to be with them.
