Save the date for Pippa Middleton's wedding! The younger sister of Duchess of Cambridge Kate Middleton is set to marry hedge fund manager James Matthews on 20 May 2017 at St Mark's church in Englefield, Berkshire. And for Pippa's day, important roles have been reportedly chalked out for Prince George and Princess Charlotte.

While George is supposed to play a page boy at his aunt's wedding, his little sister will be an adorable flower girl. Contrary to popular demand though, the Duchess of Cambridge, will not be seen as a bridesmaid at the wedding, according to reports.

Pippa came to limelight when she was the bridesmaid to Kate in her 2011 wedding to Prince William.

Once again the 33-year-old is going to be the centre of attention as she plans her nuptials with Matthews after dating for less than a year. The couple will exchange their vows at their family's local village church, and following the ceremony they are expected at Carole and Michael Middleton's home in Bucklebury for the reception.

The reception party at the Middleton home will include a luxury marquee set up for the guests in the garden. However, Pippa's modest wedding seems nothing like her sister Kate's grand nuptials as she hopes for a private wedding. Apparently Pippa and her 41-year-old fiancé are looking forward to "having children and leading a quiet life."

With the invitations already being handed out, there isn't much time left for the Duchess's sister to plan the wedding details, especially the much-anticipated dress. Speculations have been rife that popular celebrity designer Giles Deacon might create Pippa's special gown while bridal bouquets may be from the Lavender Green florist in Chelsea, London, but the Middletons are yet to confirm.

Until the big day in May, all the wedding details are expected to keep pouring in before Pippa finally says "I do" to Matthews.
