The lucky relatives and friends who will be part of the royal wedding party have been confirmed.
Kate Middleton has asked her sister Pippa to be her maid of honour.
Meanwhile, Prince Harry will be best man.
The bridesmaids include Lady Louise Windsor and Margarita Armstrong-Jones.
Louise is the seven-year-old daughter of William's uncle Prince Edward.
Meanwhile, Margarita, eight, is his second cousin Viscount Linley's little girl.
The Prince's goddaughter Grace van Cutsem, three, will also have a starring role.
As will Eliza Lopes, Camilla, Duchess of Cornwall's three-year-old granddaughter.
There are two page boys, one of whom is Billy Lowther-Pinkerton's son. His father Jamie is Private Secretary to the two Princes.
The other choice shows William has remembered his childhood nanny Tiggy Pettifer, née Legge-Bourke.
Her eight-year-old son Tom - another godchild - will also be accompanying Kate up the aisle.
