Sweet news for Zara Tindall and her brother Peter Phillips, as their younger sister Stephanie has confirmed her engagement. 

Stephanie, 23, is the youngest child of Captain Mark Phillips, who was married to Princess Anne from 1973 to 1992.

Mark and the Princess Royal welcomed children Peter and Zara during their time as a couple - and the pair both went on to re-marry after their divorce.

Princess Anne found love with her now-husband, Timothy Laurence, while Mark married Sandy Pflueger, who is now his ex-wife.

During his marriage to Sandy, Mark became a father for the third time, welcoming Stephanie.

Stephanie took to social media earlier this week to confirm the lovely news that she and boyfriend of two years William Hosier are engaged to be married.

Hinting that William had popped the question on May 9th, Stephanie captioned her sweet Instagram post, "09.05.21 • 💙💍💙"

While Stephanie, who goes by Steph, doesn't spend much time in the royal spotlight cast on her half-siblings, she has made various appearances alongside Zara and Peter for special royal occasions.

When she was 13-years-old, she acted as a flower girl at Zara's wedding to Mike Tindall and did the same at Peter's wedding to ex-wife Autumn in 2008.

Steph has plenty in common with olympian Zara too, sharing her love of horses and regularly posting snaps on Instagram of her riding.

Steph also spent much of her childhood living at Aston Farm on the Gatcombe Park in Gloucestershire—the estate the Tindalls, Princess Anne and Peter Phillips call home.

It's been predicted that we will see Zara and Peter's own daughters acting as flower girls at Steph's wedding when it goes ahead, although we are not sure when that will be.

Peter and Zara are parents to five of the Queen's ten great-grandchildren.

Peter shares 10-year-old Savannah and nine-year-old Isla with Autumn, while Zara and Mike are parents to Mia, seven, Lena, two, and newborn son Lucas, who was born in March.

Zara gave birth to Lucas on the floor of the Tindall family home, with sports star Mike sharing details of the incredible arrival on his The Good, The Bad and The Rugby podcast.

"Sunday got even better because a little baby boy arrived at my house," he said.

"Arrived very quickly, didn't make it to hospital. On the bathroom floor.

"The midwife who was going to meet us at the hospital wasn't that far away so she drove up, got there just we had assumed the position.

"The second midwife arrived just after the head arrived."
