The 23-year-old daughter of Princess Anne talks about her relationship with Princes William and Harry, her on-off romances and growing up royal.
She also discusses her competitive horse-riding and her wild reputation, which includes famously sporting a tongue stud to Buckingham Palace.
Flame TV was commissioned to produce the 30-minute interview by Five head of news, current affairs and documentaries Chris Shaw. Roger Bolton executive produced the programme, which will be screened at 19.30 on 27 June.
A Five spokeswoman said: 'It is a fantastic coup for the channel to have secured the first ever full-length television interview with Zara Phillips and is testimony to our growing reputation for current affairs documentaries.'
