Peter Phillips and Harriet Sperling are about to have the royal wedding of the year as they're due to marry at All Saints Church, Kemble, Cirencester.
Although the pair haven't yet confirmed who their maids of honour or flower girls will be, an obvious choice would be their three daughters from their previous relationships. Peter is a dad to teenagers Savannah, 15, and Isla, 14, whom he shares with ex-wife Autumn Kelly. Meanwhile, Harriet is a mum to Georgina, 13, sharing the teenager with her ex-husband, Antonio St John Sperling.
Peter's two daughters make rare public appearances, normally during only special sporting events, while Georgina remained entirely out of the public eye before her mother started dating a royal.
Here's all you need to know about Peter and Harriet's daughters…
Savannah Phillips
Savannah was born on 29 December 2010, and is the late Queen's eldest great-grandchild, much like how her father was Queen Elizabeth's eldest grandchild. She is currently 20th in line to the throne.
However, in an unusual move, Savannah's name wasn't initially given, with a statement only reading: "The Queen, the Duke of Edinburgh, the Princess Royal, Captain Mark Phillips and Autumn's family have been informed and are delighted with the news."

Savannah only makes rare appearances, but she has had some memorable moments, including telling her cousin, Prince George, to stop singing during the national anthem when she joined other royals on the Buckingham Palace balcony in 2018. Savannah was also a bridesmaid at Princess Eugenie's 2018 wedding, handing the bride-to-be her wedding bouquet.
Isla Phillips
Isla joined the family on 29 March 2012, a year and a half after her older sister was born. A statement read: "The Queen, the Duke of Edinburgh, the Princess Royal, Captain Mark Phillips and Autumn's family have been informed and are delighted with the news. Isla Elizabeth is the second child for Peter and Autumn, the second grandchild for the Princess Royal and the second great-grandchild for the Queen and the Duke of Edinburgh."

Like her older sister, Isla has made the occasional royal appearance, including at Trooping the Colour and the late Queen's Platinum Jubilee celebrations. Isla was also among Eugenie's bridesmaids at her 2018 wedding.
Georgina Sperling
The teenager made her official royal debut back in April when she accompanied King Charles and Queen Camilla, the Prince and Princess of Wales and other senior members of the royal family to the Easter Service at St George's Chapel, Windsor Castle.
HELLO! understands that Georgina has met members of the royal family, being introduced to the family at Balmoral last year. Among those whom Georgina met were the Prince and Princess of Wales and their three children.

"In the earlier years of my journey as a single mother to my daughter, resources were scarce, and the future was uncertain," she explained.
"Yet, in the absence of material security, I discovered the strength and life that comes from true selfless love. A love that is able to be solely devoted to your child. My daughter and I journeyed ten years with only each other. I liken us to an island, and it has often felt hard to imagine anyone joining that island."
