Pippa Middleton and James Matthews don't want to leave out the adorable Prince George and Princess Charlotte on their wedding day. It has been reported that the children of her older sister, Duchess of Cambridge Kate Middleton, will be playing a big part at the service.

Hello! reports that the 3-year-old prince will act as a page boy while the 1-year-old princess will act as a bridesmaid. The news is confirmed a few days after Kate visited Pippa at her house in West London. It's believed that the two met to have a last minute discussion about Prince George's and Princess Charlotte's roles.

Pippa and James will tie the knot on Saturday, May 20, according to Hello! They will have their wedding ceremony at St Marks' Church in Engefield, Berkshire and Rev. Nick Wynne-Jones will be the one who officiates. The reception will be held at the Middletons' family home in Buckleberry. The luxurious house is perfect for a beautiful wedding reception.

Besides having the young royals to participate, it's believed that Kate will play an important role. However, rumor has it that she won't be the maid-of-honor since she doesn't want to steal the spotlight from her sister. She will probably do a reading during the service.

With Prince Harry confirming his attendance, this wedding will be another chance to see if Kate and husband Prince William will attend the event together. After spending the weekend separately, the public is surely anticipating the couple's interactions. Kate and William have been rumored to be in a marital crisis after the Duke of Cambridge was caught partying and cozying up with Aussie model Sophie Taylor during a ski trip in Switzerland.
