Picture by: Splash NewsGeorge and Charlotte will be page boy and bridesmaid respectively for their aunt’s wedding on 20th May.
While the union between Pippa and James Matthews is a private one, it is now certain the press will outside the church in droves to see the young Royals in their finery.
The ceremony is to take place at St Mark’s Church in Englefield, Berkshire, a Grade I-listed building that dates back to the 13th century, and the reception at the Middleton’s home nearby.
The young Prince will be almost 4 at the time of the event, while his sister will be 2.
Pippa was Maid of Honour at The Duke and Duchess of Cambridge’s wedding in 2011, though there is no word if Catherine will return the favour to her sister. It would seem odd if Pippa chose someone else over her sister, with whom she is known to be close.
