Peter Phillips and Zara Tindall have a younger half-sister, who was born via their father’s second marriage. The siblings, who are Mark Phillips’ two older children from his marriage to Princess Anne, are known to have grown up close to Stephanie Phillips, who was born in October 1997.
Stephanie, now aged 28, is also known to have grown up on Gatscombe Park – which is where both Peter and Zara still live with their own families. She was born to Mark and his second wife, Sandy Pflueger.
The former couple separated in 2012, and despite Stephanie’s famous half-siblings, she has managed to keep a low profile.
