Prince Harry may be hoping to give his relationship with Chelsy Davy another go, it has been reported.
The 30-year-old Prince dated the Zimbabwean former lawyer on and off from 2004 until shortly after the Duke and Duchess of Cambridge wed in 2011.
The pair are now believed to be considering rekindling their romance after Prince Harry visited Africa last month.
The Prince and Ms Davy are said to have met up secretly during the trip, the Sun reported.
A source told the paper: "Harry still holds a candle for her. Chelsy has his heart.
"They saw each other recently. There's still very much something between them, but Chelsy won't commit yet because she doesn't want to lead a life in the spotlight. Harry's very sensitive to that."
Prince Harry's last serious relationship with actress and model Cressida Bonas ended last year.
He spent this summer working as a wildlife conservation volunteer on frontline projects in southern Africa and will return to the UK before attending an event to mark the 75th anniversary of the Battle of Britain, which takes place on the same day as his 31st birthday, 15 September.
He will return to Africa to visit Lesotho and South Africa in November and December.
The source suggested it was "no coincidence that Harry decided to spend more time in Africa later this year.
"He has never fallen out of love with Chelsy. She's not like other girls; she's strong, independent and a rule-breaker. She does everything on her own terms."
