Princess Eugenie and Jack Brooksbank have released the names of the friends and family who will accompany them down the aisle at their wedding on Friday.
Eugenie's second cousins Prince George and Princess Charlotte will reprise their positions as pageboy and bridesmaid for their second role in royal nuptials following Meghan and Harry's wedding in May.
However, Eugenie has enlisted several other youngsters to act as her flowergirls including sisters Savannah, 7, and Isla Philips, 6, four-year-old Mia Tindall, Maud Windsor, 5, and most surprising six-year-old Theodora Williams, the daughter of Robbie Williams and Ayda Fields, reports Daily Mail.
The showbiz couple and X Factor judges have been friends with Eugenie, 28, and her sister Princess Beatrice, 29, for some years.
Louis de Givenchy, son of Frenchman Olivier de Givenchy, a senior banker at JP Morgan will join Prince George as one of two page boys.
The couple have asked the bride's cousins and children of Prince Edward and Sophie Wessex, Lady Louise Mountbatten-Windsor, 14 and her brother James Viscount Severn, 10, to act as Special Attendants.
Predictably, taking the role of Maid of Honour is the bride's older sister Princess Beatrice whose role in the wedding has been speculated for several months.
The groom has followed suit asking his brother, Thomas Brooksbank, to be his Best Man and stand by his side while he says his I dos.
WHO'S WHO IN EUGENIE'S WEDDING PARTY
• Prince George and Princess Charlotte
The children of the Duke and Duchess of Cambridge are well known for "stealing the show" at weddings and Eugenie's is sure to be no different.
Charlotte, 3 and George, 5 will take on the role of flower girl and pageboy for the fourth time on Friday.
The brother and sister have taken on the responsibility on two other occasions, first at their aunt Pippa Middleton's wedding in May last year and then again last month at Kate's close friend Sophie Carter's nuptials.
It will be their second time at St George's chapel having been walked the aisle behind Meghan at her marriage to Prince Harry in May.
• Theodora Williams
Robbie Williams and Ayda welcomed their daughter Theodora in September 2012, and son Charlton Valentine in October 2014.
According to the Sunday Times Williams, met the princess on holiday in the Caribbean and was 'entranced' by Eugenie's manners that he put Teddy on the list for her school, Marlborough College.
The couple are protective over their young children, and choose not to show their children's faces when they post on social media.
• Savannah and Isla Phillips
Savannah and Isla are the daughters of Peter Phillips, Princess Anne's eldest and only son, and his wife Autumn.
Savannah famously caused a fuss at Trooping the Colour this year when she covered Prince George's mouth during the Buckingham Palace flyover.
Though the seven-year-old is sure to be on her best behaviour on Friday.
• Mia Tindall
Mia is the eldest daughter of Zara and Mike Tindall who welcomed their second daughter Lena in June.
The four-year-old is a favourite among royal fans, stealing the nation's heart when she posed alongside the Queen's fellow great grandchildren for a portrait celebrating her 90th year.
She is sure to give Charlotte a run for her money when she takes on her first public bridesmaid role on Friday.
• Maud Windsor
Five-year-old Maud is the daughter of Lord and Lady Frederick Windsor also known as Sophie Winkleman- and the bride's goddaughter.
She attends the same school as Prince George and the royal youngsters are in the same class at Thomas' in Battersea.
Frederick is the son of Prince and Princess Michael of Kent, with his father being cousin to the Queen.
This makes Maud and George distant cousins who had plenty of time to bond at school
• Lady Louise
The young royal was a bridesmaid at the Duke and Duchess of Cambridge's wedding and is 11th in line to the British throne.
She was born with a squint, but can now see perfectly after having corrective surgery.
A firm favourite of the Queen, she has accompanied her parents to royal church services and at every turn has shown herself to be gracious and well-mannered.
Lady Louise is already an accomplished horsewoman and has previously competed in carriage driving at the Royal Windsor Horse Show.
• Viscount Severn
The Queen's youngest grandchild, James, Viscount Severn, will join his sister Louise as a Special Attendant on the big day.
He is one of the lesser seen members of the royal family but caused a stir earlier this year when he was spotted behind the wheel of the family's Land Rover on the Windsor Estate.
Under the law, motorists do not need a provisional licence to drive a car on private land - however, insurance companies would refused to pay out in the event of an accident.
• Louis De Givenchy
Louis is one of just two pageboys in the procession, joining forces with Prince George.
Louis is the son of Frenchman Olivier de Givenchy, a senior banker at JP Morgan, and his Australian wife Zoe, are also friends with Robbie and Ayda.
• Thomas Brooksbank
Thomas, known as Tom, has been given the role of best man.
Tom keeps a low profile managing UK investor relationships and graduated from the University of Leeds in 2011.
• Princess Beatrice
The bride's older sister made an obvious choice as maid of honour, with rumours swirling of her role for many months.
On Tuesday she was spotted swiftly walking down the street away from Ralph & Russo's Mayfair store, which is 'strictly by appointment' only.
Beatrice looked to be fulfilling bridesmaid duties ahead of her sibling's wedding to her groom Jack Brooksbank, a 32-year-old tequila brand ambassador.
