Marlene Koenig, a British and European royalty expert, tells BAZAAR.com she'd be 'shocked' if we didn't see Prince George and Princess Charlotte dolled up and walking down the aisle.

When asked whether the two would follow Meghan down the aisle, a spokesperson for the royal family seemed to confirm their participation: 'The wedding will be a family event,' the spokesman told . 'You can expect the family to be involved.' The royal tots have already met Markle 'several times' Kensington Palace told The Times. Presumably, the connection they've formed with Markle, and that Markle has formed with their mother, should earn them a spot in the proceedings on May 19th.

George, a page boy, walked the aisle carrying a flower basket, and little sis Charlotte, donned an adorable flower crown, as a bridesmaid. Charlotte will likely wear a similar white dress to Harry and Meghan's wedding as she wore to Pippa's, perhaps going for something in an all white color palette rather than with a touch of blush.

Kate chose not to participate in the her sister's wedding, so as not to overshadow Pippa on her big day. 'Kate would upstage her sister,' royals expert Judy Wade . '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.

'There will be several rehearsals for this wedding, as there is for all royal weddings, and I can only assume that Catherine or Nanny Maria will spend some time talking to the children about their roles, responsibilities, as a part of the bridal party,' says Koenig. 'Young kids in wedding parties will fuss and fidget. If George or Charlotte make funny faces or does something silly, their antics will be recorded for posterity.' After all, who could forget the '', Grace Van Cutsem, at William and Kate's royal wedding?
