Prince George and Princess Charlotte Will Be Bridal Attendants

At this point, Prince George and Princess Charlotte are practically professional wedding participants.

The mini royals will reprise their roles as page boy and bridesmaid for the fifth time this summer, in honor of the nuptials of Prince William's close friend Thomas van Straubenzee to Lucy Lanigan-O’Keeffe, who's a teacher at Prince George's school, Hello! reports. And they're not the only ones expected to guest star in the wedding: Prince William is expected to also serve as an usher.

Van Straubenzee and The Duke of Sussex have been longtime friends, and according to The Sunday Times, per Town and Country, "nobody would be surprised if Prince William or his wife, Kate, were involved" in introducing he and Lanigan-O’Keeffe

The 5- and 4-year-old Prince and Princess have previously served in the weddings of Pippa Middleton and James Matthews, Prince Harry and Meghan Markle, Princess Eugenie and Jack Brooksbank, and their parents' friends Sophie Carter and Robert Snuggs. And yes—they looked positively adorable every time.

But in addition for knowing how to rock a formal wedding look, Prince George has also proven himself to be an A+ wedding party member. When 2-year-old bridesmaid Zalie Warren "had a bit of a meltdown" before Meghan Markle and Prince Harry's ceremony last year, George stepped in and tried to help. "She started crying when they were waiting for Meghan," royal correspondents Emily Andrews revealed in the On Heir podcast, per Harper's Bazaar. "It was only a couple of minutes. So Nanny Maria Borrallo kind of looked after her, and George apparently was trying to comfort her as well, which is very sweet."

We're willing to bet it's only a matter of time before Prince Louis and baby Archie will be joining Prince George and Prince Charlotte as wedding participants, and we can't wait to see those photos.
