Of course, the children’s parents, Prince William, 34, and Duchess Kate, 35, — Pippa’s older sister — will also attend the ceremony, as will their uncle, Prince Harry, 32.

Prince William may even have flashbacks of his own time as a dapper little page boy.

William was just 4 years old when he took part in the 1986 wedding between Prince Andrew and Princess Sarah “Fergie” Ferguson.
