Pippa Middleton's grand wedding with hedge-fund boss James Matthews seems to be the centre of attraction for paparazzi. The wedding will take place on May 20 at a quiet estate church in Berkshire. The younger sister of Kate Middleton is gearing up for her grand day and looks like she is leaving no loopholes in making it an extravagant event.

One of the key highlights of the wedding will be Princess Charlotte dressed as an adorable bridesmaid and proud George accompanying Pippa down the aisle as a page boy.

"And now, following months of speculation, the bride-to-be has finally confirmed that her niece and nephew will be given these roles on her big day," a report in Daily Mail stated.

Giles Deacon is rumoured to be the designer. According to the report, "he was spotted carrying garment bags into the £17 million house with his and hers bathrooms she and James share in London."

Although, it looks like Kate Middleton will not be playing any key role, it is reported that Kate doesn't want to take away the limelight from her little sister on the D-day and has decided to take a backseat during the event.

Remember, how Pippa grabbed away the limelight at William and Kate's wedding in 2011. Royal author Judy Wade told PEOPLE, "It's a tricky situation for Pippa. She would want her sister by her side, as who else would she trust to make things go well? But if your sister is a future queen, she is going to upstage the bride and draw attention. Kate would want to be in the background as much as possible."

Another key controversy surrounding the wedding is the inclusion of Prince Harry's girlfriend Meghan Markle. Pippa has kept her wedding invite 'no ring, no bring'—which means guests can bring their partners only if they are engaged or married. In that case, Harry has to attend the event without his girl.
