Following the exciting announcement that Peter Phillips is engaged to his girlfriend Harriet Sperling, the couple will be making plans for their big day.

While no date or details have been publicly announced, it's almost certain that Peter and Harriet will involve their children in the ceremony.

Peter, who is a first cousin of Prince William, shares two daughters, Savannah, 14, and Isla, 13, with his ex-wife Autumn. Harriet, meanwhile, is a single mother to her daughter Georgia, who was born in 2012.

It's likely that Savannah and Isla will act as bridesmaids on their soon-to-be-stepmother's big day, given how close the blended family are, not to mention Georgia also playing a special role.

HELLO!'s Royal Correspondent, Danielle Stacey, said: "While we're waiting to see what kind of wedding the couple will opt for, I'm sure Peter's daughters, Savannah and Isla, and Harriet's daughter, Georgia, will have starring roles on the day.

"A source previously told me how they appeared to be a 'tight unit' together when they all attended the Gloucestershire Festival of Polo last year, and Harriet was described to me as 'very motherly' and 'very good with the kids'." 

Savannah and Isla's bridesmaid roles

If they do play such starring roles, it wouldn't be the first time.

Savannah and Isla were previously bridesmaids at Princess Eugenie's wedding in Windsor in October 2018. The girls looked sweet in white dresses, matching with fellow royal bridesmaids Princess Charlotte and Mia Tindall.

Four years later, Savannah and Isla once again played a special part at the wedding of Stephanie Phillips, their father's half-sister, in July 2022. The girls were dressed to the nines at the church wedding in Tetbury, Gloucestershire, wearing white and blue frocks.

Given Peter's close bond with his sister Zara Tindall, it's also possible that Zara's children Mia, Lena, and Lucas Tindall may also play a part in their uncle's big day.

Relationship history

The pair were first romantically linked in May 2024 when they made a joint appearance at the Badminton Horse Trials. They were seen walking hand-in-hand as they supported Peter's sister, Zara, at the equestrian event.

At Royal Ascot the following month, Harriet, an NHS paediatrician and freelance writer, met Peter's uncle, King Charles

Since then, the couple have made loved-up appearances at charity polo matches, Royal Ascot, Wimbledon, and other sporting social events.

Harriet has also spoken publicly about her royal relationship. "My daughter and I journeyed ten years with only each other," she told Christian magazine Woman Alive. "I liken us to an island and it has often felt hard to imagine anyone joining that island.

"But of course, beauty comes from relationships, relationships with our maker and relationships with each other. It is often tough parenting alone, but although there is a stigma to endure, God is able to step in and turn it for good."
