When the Duke and Duchess of Cambridge got married, one overwhelmed little bridesmaid stole the show as she was photographed crossly covering her ears from the noise of the crowd.
As Prince Harry and Meghan Markle tie the knot they will have no such fears, after choosing a brood of children already well used to the limelight.
Ten little girls and boys are to take a starring role in the Royal wedding, from Prince George and Princess Charlotte to a host of youngsters who are already Instagram stars. But who are they?
Who are the bridesmaids?
- Princess Charlotte of Cambridge, aged three, is Prince Harry and Meghan Markle's niece.
- Florence van Cutsem, aged three, is goddaughter of Prince Harry and daughter of Alice van Cutsem and Major Nicholas van Cutsem.
- Remi Litt, aged six, is goddaughter of Ms Markle and daughter of Benita Litt and Darren Litt.
- Rylan Litt, aged seven, is goddaughter of Ms Markle, daughter of Benita Litt and Darren Litt.
- Ivy Mulroney, aged four, is Jessica Mulroney and Benedict Mulroney's daughter.
- Zalie Warren, aged two , is Prince Harry's goddaughter and the daughter of Zoe Warren and Jake Warren
A look back at royal bridesmaids and pageboys
Who are the pageboys?
- Prince George of Cambridge, aged four, is Prince Harry and Meghan Markle's nephew.
- Jasper Dyer, aged six, is godson of Prince Harry and the son of Amanda Dyer and Mark Dyer.
- Brian Mulroney, aged seven, is the son of Jessica Mulroney and Benedict Mulroney.
- John Mulroney, aged seven, is the son of Jessica Mulroney and Benedict Mulroney.
Prince George of Cambridge will again be thrust into the limelight as he is expected to take the lead as one of four pageboys for his uncle and auntie's wedding.
William and Kate's eldest child is said to be shyer than his younger sister Charlotte, and the Duke has told how his son loves helicopters, flying and is obsessed with all things police-related.
Like Charlotte, George is rarely seen in public. The Duke and Duchess try to ensure their children are protected from media intrusion.
But the pair have appeared at key royal events such as the annual Trooping the Colour parade, and have joined William and Kate on official overseas tours.
Son of the Duke and Duchess of Cambridge, the third in line to the throne is no stranger to big public appearances even at the age of just four.
He will call upon the experience gained from performing a similar role at the wedding of Pippa Middleton, the Duchess of Cambridge's younger sister, to James Matthews in May last year.
It will be the second time in a month that the world's media hones in on his family following the birth of his younger brother Prince Louis on April 23.
Princess Charlotte is blossoming into a natural when it comes to public appearances. The way she played to the cameras as she arrived outside St Mary's Hospital in Paddington, central London, showed maturity beyond her years.
The three-year-old waved at photographers as her father, the Duke of Cambridge, walked her to meet her baby brother - Prince Louis.
Making her way up the steps to the Lindo Wing, she turned and waved again - a picture that was beamed across the world.
Her parents have told how the fourth in line to the throne rules the roost, saying she is "very sweet" but also feisty.
It is expected her mother, the Duchess of Cambridge, will play a supervisory role for the young pageboys and bridesmaids, something she did when her younger sister, Pippa, married James Matthews last year.
The Duchess was spotted giving a polite warning to the youngsters in her charge, who included George and Charlotte, holding her finger to her lips to make sure they were quiet as they entered the church.
Ivy Mulroney, four, and her seven-year-old twin brothers are a daily staple of Mrs Mulroney’s Instagram page, posing willingly for home photoshoots with their mother.
Ivy is the four-year-old youngest child of Meghan's stylist and best friend Jessica Mulroney. Her name is actually Isabel Veronica but she is nicknamed Ivy.
The little girl often appears on her mother's Instagram page, helping her get ready, putting on makeup and picking outfits, while brothers Brian and John lark about together.
Jessica Mulroney runs a bridal store in Toronto, where Meghan used to film Suits, and is said to have helped the bride choose her wedding gown.
Mrs Mulroney, who is married to Benedict Mulroney, the son of former Canadian prime minister Brian Mulroney, was photographed arriving at Heathrow Airport with her family on Tuesday night.
When Ms Markle made her third official appearance at the Invictus Games in October, it was with two very important women by her side; her mother, Doria and Jessica Mulroney - arguably Canada’s best-connected fashion power player.
Her influence has already helped to propel a lucky clutch of Canadian fashion designers to global fame thanks to her role as stylist to Sophie Gregoire-Trudeau, the wife of Canada’s charismatic prime minister, Justin Trudeau.
It was in Canada where the two met. Both were living in Toronto when Ms Markle was filming the US hit series Suits.
Having initially bonded over a shared love of yoga, they become close enough to go on holiday together and Meghan became close to the family - including Ivy, Brian and John.
Puff: Who is Jessica Mulroney?
Brian and John Mulroney
The fraternal twin sons of Jessica and Ben are seven years old - and older siblings to Ivy.
In an interview with thestar.com in 2014, Mrs Mulroney described how the boys were best friends. "Ben was at the MMVAs (iHeartRadio Much Music Video Awards) and John did something really sweet," she said. "He hugged Brian from behind and said, 'Brian, you make me great'. "
The article described the children, who had two nannies, as "incredibly well-behaved".
Florence van Cutsem
Three-year-old Florence is Prince Harry's goddaughter, and the daughter of his long-standing family friend Major Nicholas van Cutsem and Alice van Cutsem.
She is a cousin of Grace Van Cutsem, best remembered for her balcony appearance with her hands over her ears at the wedding of Prince William and Kate Middleton.
Major van Cutsem, a major with the Household Cavalry's Life Guards, has been a friend of Harry and William's since childhood.
Remi and Rylan Litt
The Litt sisters, who have appeared in Instagram pictures with Ms Markle, are the children of Darren and Benita, a handbag designer and close friend of the bride.
Ms Markle is Remi, six, and Rylan, seven's godmother and in a since deleted Instagram post, the actress shared a picture of herself with the family - including her two "fairy god-daughters" - showing them happily posing in front of a Christmas tree after spending the holidays together in 2016.
Benita also runs her own brand agency under her name where she helps others to start businesses.
Zalie Warren is the daughter of Jake Warren, son of the Queen's bloodstock and racing adviser John Warren, and his wife Zoe. The father-and-son team run Highclere Stud in Newbury together.
Mr Warren is an old school friend of Prince Harry’s from Eton who asked him to be godfather to Zalie, one of his twin daughters.
Zalie is the youngest of the bridesmaids at just two years old.
Prince Harry and Meghan Markle: The story of their relationship, in pictures
Six-year-old Jasper Dyer is also a godson of Harry's and the son of his trusted mentor Mark Dyer and Mr Dyer's wife Amanda.
Former Welsh Guards office Mr Dyer, who was photographed accompanying Ms Markle to the polo when she was dating Prince Harry, has been a long-term mentor of the Prince, taking him under his wing during the 1990s and early 2000s when the teenager was coming to terms with the death of his mother Diana, Princess of Wales.
A former equerry to the Prince of Wales, he was entrusted by Charles to keep an eye on Harry.
The pair travelled together in Harry's gap year and he inspired the prince's charity work in Lesotho, southern Africa, after arranging Harry's first ever stay in the country.
A very traditional ceremony
The couple will be make their vows at St George's Chapel, which last hosted a royal wedding in May 2008 when Peter Phillips - son of The Princess Royal - married Autumn Kelly.
The traditional ceremony will be conducted by The Dean of Windsor, The Rt Revd. David Conner while the Archbishop of Canterbury, Justin Welby, will officiate as the couple make their marriage vows.
Pioneering American bishop, the Most Rev Bishop Michael Curry, from Chicago, Illinois, has been invited to deliver the address as the couple strive to reflect their transatlantic relationship amid the tradition of St George's Chapel.
Bishop Curry, who has been praised for his "infectious laughter and self-deprecating humour", is the first African-American bishop to have served as the Episcopal Church's presiding bishop, a role he has held since November 2015.
The music will also have an American influence according to Christopher Warren-Green, who will conduct musicians on the day.
