With the royal wedding now just days away, speculation about who will and won't be in attendance has reached fever pitch. In recent days, much attention has been cast toward bride Meghan Markle's father, Thomas Markle, with questions regarding his health and his relationship with the paparazzi splashed across the front pages of numerous British tabloids.

“I'm just too ill to walk Meghan down the aisle,” read the Daily Mirror's front page Wednesday. “Meghan's dad 'wants to come but heart op might stop him,' ” said the Daily Mail.

Whether Thomas Markle will be there to walk his daughter down the aisle Saturday still remains unclear.

One thing is certain, though: Prince George and Princess Charlotte will be there, and they'll be taking center stage. Traditionally, children play an important role in royal weddings, and this one is no exception.

George, 4, and Charlotte, 3, are among 10 children selected by Prince Harry and Markle to feature as part of their big day. In total the couple will have six bridesmaids and four pageboys, Kensington Palace said Wednesday. The other children include Harry's godchildren and Markle's goddaughters. The ages of the children involved range from 2 to 7.

This is not the first time the children of the Duke and Duchess of Cambridge have had starring roles in a family wedding. In May last year, Charlotte was a bridesmaid and George was a pageboy for their mother's younger sister, Pippa Matthews.

Kensington Palace shared a full list of the children on Wednesday but did not provide further details about what they would be wearing on the special day. After the announcement, it didn't take long for Charlotte's name to trend on Twitter. Many declared the news as cuteness overload.

“Okay but princess Charlotte is so cute I might actually combust into glitter,” read one tweet.

“Princess Charlotte is a bridesmaid, I'm crying,” read another.

Charlotte is already winning hearts at home and abroad. She was recently seen waving charmingly to photographers and bystanders outside St Mary's hospital in London, where her mother had given birth to a third child, Louis. As he is so young, the newborn prince will not be at the wedding.

Yes, the world can't wait to see what Markle will be wearing on Saturday, but Charlotte might just steal the show.
