According to some reports, The Duchess of Cambridge, Kate Middleton, will not be a bridesmaid at her sister's wedding.
Reports claim that the reason Kate is not going to be acting as bridesmaid for Pippa’s wedding is due to sibling rivalry or because Pippa wants to make sure Kate does not steal the scene.
There is some credibility in the theory put forward that Kate herself would not wish to “upstage her sister,” as put forward by veteran royal author Judy Wade, but another reason Kate won’t be a bridesmaid at Pippa’s wedding to city whiz-kid James Mathews is very simple and, sadly for the royal conspiracy theorists, much less exciting.
British tradition dictates that bridesmaids should always be unmarried and should be younger than the bride; indeed, many aristocratic British brides have children as their bridesmaids.
Pippa will almost certainly ask her sister to read a piece of poetry or a passage from the Song of Solomon at her wedding.
