Prince Harry and Meghan Markle have announced the bridesmaids and pageboys for the royal wedding.
Kensington Palace has announced that Ms Markle will have no adult bridesmaids 'because she's unable to choose between her friends', and will instead be surrounded by children as page boys, bridesmaids and flower girls.
The bridesmaids are Princess Charlotte, Florence van Custem, Remi Litt, Rylan Litt, Ivy Mulroney and Zalie Warren.
The pageboys, who are outnumbered six to four, are Prince George, Jasper Dyer, Brian Mulroney and John Mulroney.
Royal siblings Prince George and Princess Charlotte are no strangers to the roles having performed them at the wedding of Pippa Middleton, the Duchess of Cambridge's younger sister, to James Matthews in May last year.
The other pageboys are Harry's godson, Jasper Dyer, aged six, and seven-year-old twin brothers Brian and John Mulroney.
Harry has paid tribute to former mentor and close friend Mark Dyer by requesting his son Jasper as a pageboy, while Ms Markle has publicly recognised one of her best friends, stylist Jessica Mulroney, by choosing her twin sons to take part in the wedding.
Mr Dyer, a redhead like the prince, was a supportive big brother figure for Harry during the 1990s and early 2000s when the teenager was coming to terms with the death of his mother Diana, Princess of Wales.
Mrs Mulroney, who is married to Ben Mulroney, the son of former Canadian prime minister Brian Mulroney, was photographed arriving at Heathrow Airport with her family on Tuesday night.
Zalie Warren is the daughter of Jake Warren, son of the Queen's bloodstock and racing adviser John Warren, and his wife Zoe.
The palace has already announced that Ms Markle is not having a maid of honour because she did not want to choose just one person from her close-knit group of friends.
Kate is likely to 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.
The Duke of Cambridge will be Harry's best man, missing the FA Cup final to be at his brother's side.
The Duke, who has always been the front-runner for the supporting role at the wedding, is "honoured" to have been asked, Kensington Palace said.

Prince George
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
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
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.
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 Ms Markle became close to the family - including Ivy, Brian and John.
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.
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
Remi Litt is the six-year-old daughter of Ms Markle's close friend Benita Litt and her husband Darren Litt. Rylan is her older sister, aged seven.
Ms Markle is Remi and Rylan'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 runs her own brand agency under her name where she helps others to start businesses.
Zalie Warren
Zalie is the youngest of the bridesmaids at just two years old.
She is another of Harry's goddaughters and the daughter of one of his best friends, Jake Warren and Mr Warren's wife Zoe.
The Warren family are closely connected to the royals through horse-racing. Jake's father John Warren is the Queen's racing manager.
The father-and-son team run Highclere Stud in Newbury together.
Jasper Dyer
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 has been a key father figure to the prince since childhood.
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.
Brian and John Mulroney
The fraternal twin sons of Jessica and Ben Mulroney are seven years old - and older siblings to Ivy Mulroney.
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".
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.
Ms Markle, who was a UN women's advocate, is unlikely to opt to obey the prince. The couple will probably choose the Series One (1966) Book of Common Prayer ceremony, just as the Duke and Duchess of Cambridge did, which allows the bride to drop "obey him" and "serve him" from the religious proceedings.
The regiments Prince Harry served with in Afghanistan will a have a “special place” during the ceremony.
The 3 Regiment Army Air Corps, where the prince served as an Apache Pilot in Helmand Province will be represented, as well as The Royal Gurkha Rifles, his comrades in Afghanistan in 2007, and RAF Honington, where he is Honorary Air Commandant.
Household Cavalry troopers will line the staircase at St George's Chapel, while streets within the precincts of the castle will be lined by members of the Windsor Castle Guard from 1st Battalion Irish Guards, and by Armed Forces personnel from the Royal Navy Small Ships and Diving, which has the Prince as Commodore-in-Chief, and the Royal Marines, where he is Captain General.
Will Prince William be at the FA Cup?
It has been announced that Prince William will be Prince Harry's best man. The decision means the Duke, who is President of the Football Association, will not attend the FA Cup final, which is happening on the same day as the wedding.
Scheduled to start at 17:15, the FA Cup final will see Chelsea and Manchester United go head to head for the title. Windsor Castle is about an hour's drive from Wembley Stadium, which would have taken the Duke of Cambridge away from the proceedings for at least two hours.
Asked how he felt about being chosen as Prince Harry’s best man, the Duke said: “It feels great. [I am] thrilled and delighted obviously. Revenge is sweet. I’ll be looking forward to it.”
The Duke’s own stag do is reported to have been held on a Devon estate, Hartland Abbey, where he and close friends indulged in drinking, clay pigeon shooting, surfing and games.
Prince Harry went on to tease his brother mercilessly during a none-the-less heartfelt best man’s speech at the wedding reception, allegedly wearing a fez, mimicking the lovestruck conversations between a young Kate and William, and ridiculing his bald spot.
