Any avid royal fan would agree that the moment Kensington Palace confirmed the Duke and Duchess of Cambridge's two cherubs Prince George and Princess Charlotte were going to have an official part in Pippa's wedding - we were all destined to see something great unfold.
While they're ridiculously cute, putting young kids in a bridal party always makes for some very amusing moments.
And the royal siblings delivered so many hilarious moments during their double-act, we almost forgot we were watching the wedding of the year.
Prince George was really killing it as pageboy on his Aunty's big day.
The growing three-year-old looked adorable in gold pants and a Peter Pan collared white shirt, and don't even get us started on those knee-high socks.
But weddings are very long. Especially when you're a kid with better things to do, like tip baskets upside down.
And George was less than impressed by the one hour long church ceremony. By the time he and his bridal party pals walked outside with the newly crowned Mr and Mrs James Matthews, Prince George had had enough.
Footage from the bridal party leaving the church (which you can watch in the video player above!) appears to show Prince George accidentally stepping on Pippa's £40,000 wedding dress before Kate quickly steps in.
But Duchess Catherine wasn't having bar of it.
Kate had admitted prior to the wedding that she was concerned that her little ones may play up.
But nothing was going to ruin her little sister's big day.
So Catherine switched into mum mode to give her son a right royal telling off... And this isn't the first time we've seen Kate have stern words with her first-born.
Our favourite scolding has to be during Princess Charlotte's christening in 2015.
The talking to from mum didn't take too long and soon enough, our favourite Prince resumed his unimpressed stance.
And George wasn't the only pageboy acting out.
One of his fellow pageboys was snapped making a rather rude finger gesture and poking his tongue out, while Duchess Catherine stood behind him.
By the look on Kate's face, we're guessing it didn't go down very well.
Princess Charlotte, however, was simply divine as a bridesmaid.
The two-year-old Princess stole her Aunty's thunder, dressed in a bespoke outfit by designer Pepa & Co the two-year-old won hearts around the world.
Charlotte was a vision in a sweet ivory dress with a dusty pink bow detail, completed with the most perfect flower crown.
While the youngster was on her best behaviour during the ceremony, she did have a moment where it all became a bit too much.
Prince George quickly came to his crying sister's aid, distracting her with a floral wreath.
This is the first time we've seen the siblings this year, and it appears George's boisterous nature has rubbed off on Charlotte.
Kate, who revealed the siblings are “really good friends", was in stitches from her daughter's antics before entering the church.
And the Duchess' description of Charlotte being the “one in charge” shone through.
The sassy two-year-old clearly was vying for head bridesmaid, showing up everyone else with her sweet smiles and adorable poses.
Princess Charlotte proved that she may be fourth in line to the throne but nothing is beneath her.
The royal discovered she could amuse herself by licking her flower basket.
And we salute her for it!
It will come as no surprise that many comparisons have been made of the next generation of royal kids looking just like their famous parents.
Charlotte has inherited her mummy's signature brunette locks and delicate features, while Prince George is the spitting image of his famous dad.
And it turns out he's following in his footsteps too!
Three decades ago, a Prince William stepped into the role of pageboy for his uncle Prince Andrew's nuptials to Sarah Ferguson.
The year was 1986, dressed in a sailor's outfit, the young chap showed us where George gets his bemused expression from.
Reports from the time revealed that Prince William was especially naughty, pulling faces, poking out his tongue and yawning throughout the proceedings.
David Dimbleby commented during the live broadcast that Wills looked "rather doubtful and rather cross".
William got a do-over in 1988 where he was the perfect gentlemen stepping into his role at the wedding of Camilla Dunne and Rupert Soames, a grandson of former U.K. Prime Minister Winston Churchill.
