Pippa Middleton will be tying the knot with billionaire James Matthews in May 2017 and it is going to be a star-studded yet private affair. Though Kate Middleton will not be returning the favor to her younger sister by acting as the bridesmaid, her children, Prince George and Princess Charlotte will play key roles in their aunt's wedding.

Prince George and Princess Charlotte are expected to play page boy and flower girl at the upcoming wedding of Pippa Middleton, report Mirror. Kate Middleton and Prince William will also attend Pippa Middleton and James Matthews wedding along with Prince Harry, but the Duchess of Cambridge will not be playing the bridesmaid and it is still not known who will do the honors. What is known is that Matthews' brother and reality star Spencer Matthews will be the best man at the wedding.

The wedding will be a private affair as the couple will be exchanging the vows at a local village church and later, a reception is scheduled at Michael and Carole Middleton's home in Bucklebury in their back garden, claims USA Today. The invitations have been already handed out and the would-be couple looks forward to leading a quiet life and having children.

Notably, Pippa Middleton came into limelight when she was spotted wearing a huge diamond ring a few months back and then it came to the light that the billionaire hedge fund manager popped the question to her when they were enjoying a getaway in the Lake District. Now the wedding is scheduled for May 20 and though a traditional affair, it will see around 150 guests including some famous faces.

On Pippa's wedding day, she is expected to wear something extraordinary. It is being said that popular designer Giles Deacon will create her wedding gown and the bouquets will come from Lavender Green florist in Chelsea. However, a formal announcement is yet to be made by the Middletons.

It is worth mentioning here that for some time rumors have been floating around about how Pippa tried to separate Kate Middleton and Prince William so that her sister's supposed third pregnancy does not steal the limelight from her wedding.
