5 pictures that prove Princess Charlotte is already a superstar

Harry and Meghan were married Saturday at St. George's Chapel in front of around 600 guests, including celebrities ranging from Oprah Winfrey to Elton John, Victoria and David Beckham and George and Amal Clooney.

And here, just like Charlotte in a auto, Harry sticks his tongue out at cameras after the birth of his cousin Princess Beatrice.

The young children of the Duke and Duchess of Cambridge reprised the roles they had at their Pippa Middleton's wedding to James Matthews last May, so they have already had practice walking up the aisle. Meghan Markle and Prince Harry are obviously the main attractions at their royal wedding today, but their itty bitty bridal party is definitely giving them a run for their money. Meghan Markle's other godchildren, six- and seven-year-old Remi and Rylan Litt, were chosen for the bridal party, as well.

At times it seemed as though nearly everywhere Meghan Markle went on her wedding day, a little band of helpers followed. "They feel so lucky to have been able to share their day with all those gathered in Windsor and also all those who watched the wedding on television across the UK, Commonwealth, and around the world".

They were made from ivory silk with high-waisted with short puff sleeves and hand finished with a double silk ribbon detail tied at the back in a bow.

Meghan, meanwhile, will not have a maid of honor. The girls wore white leather Aquazurra shoes monogrammed with their initials and the wedding date as a keepsake gift from Meghan. "She has a very close-knit circle of friends and she didn't want to choose one over another", a spokesman from Kensington Palace told ET earlier this month.

But waiting always got everyone bored, and Princess Charlotte was no exception.

Kate and William's third child, Prince Louis, was not expected to attend, as ET learned that the 3-week-old royal would be staying home.
