Her social media profiles highlight her shared love of horses and riding - much like Zara, who has carved out a career as a professional equestrian.

Like his elder daughter Zara, Mark was an Olympic gold medal-winning horseman for Great Britain.

Her mother Sandy was also part of the US Olympic dressage team at the 1984 Olympic games in Los Angeles.

Stephanie, herself, has also carved out a career as an equestrian and has competed at Barbury International, Wellington International Horse Trials and the West Wiltshire trials.

Stephanie appears to share a close bond with her half-siblings.

She acted as a flower girl at Zara's wedding to Mike Tindall in 2011 and also appeared at Peter's wedding to Autumn Kelly back in 2008.

At her wedding in 2022, Stephanie had Peter's daughters Savannah, 13, and Isla, 12, and Zara's daughters Mia, 10, and Lena, 6, as her flower girls.
