Since the day Prince Harry and Meghan Markle's engagement was announced, royal fans have been imagining two-year-old Princess Charlotte as one of the bridesmaids. It has now been revealed that not only will the little Princess play that important role at the wedding, but her brother, Prince George too, will follow Markle down the aisle as a pageboy.

According to the Sunday Times, Prince Harry's nephew and niece have both been confirmed as pageboy and bridesmaid respectively.

"The wedding will be a family event. You can expect the family to be involved," read a Kensington Palace statement.

Marlene Koenig, a British and European royalty expert told Harper's Bazaar.com: "George and Charlotte are Harry's only niece and nephew, so it would be a real shocker if they were not included. In Britain, the bride goes down the aisle first, followed by attendants or bridesmaids and pageboys holding the train."

The royal siblings are no strangers to weddings, having made an appearance at aunt Pippa Middleton's nuptials to James Matthews at St. Mark's Church in Berkshire, England in May this year.

Their adorable moments at the marriage ceremony grabbed as much headlines as did the wedding itself. One of memorable scenes was when four-year-old Prince was left in tears after he received a scolding from his mother, the duchess. The pictures of Prince George crying quickly went viral.

Apart from Prince George and Princess Charlotte, reports suggest that Prince Harry has already asked the Duke of Cambridge to be a supporter (best man in royal terms) at his wedding. Prince Harry played the same role at his elder brother's wedding in April 2011.

The Duchess of Cambridge, however, will not play a significant role at the wedding as she is expected to give birth to her third child around the time of the nuptials.

E! News also reports that Isabel Veronica Mulroney, the daughter of Markle's best friend Jessica Mulroney and Ben Mulroney, will be one of the bridesmaids alongside Princess Charlotte.

Prince George was recently in the news again when he wrote a letter to Santa Claus saying he wanted a toy police car for Christmas. Prince William, who was on an official tour in Finland last week, personally delivered the letter to Santa at a festive market in Helsinki. He even made sure that Father Christmas knew that his son had been a "nice boy" this year.

Prince Harry and Markle have been tight-lipped about their wedding arrangements so far, but it was reported that they will have a banana cake at the ceremony instead of the traditional fruit cake. The wedding is set to take place in May 2018 at St George's Chapel, Windsor Castle.
