Prince Harry and Chelsy Davy are reportedly set to jet off on a luxury holiday in southern Africa this week to decide whether to make-up or break-up for good.

The couple are said to have split last month after Chelsy got annoyed at Harry’s partying behaviour but began to reconcile again last weekend.

A source told the Sun that the pair still consider themselves together but realise that their relationship is on very fragile ground: “It’s been a dreadful three months for them and this trip is about going back to basics. If it doesn’t work out for them both, that could be it.”

They are expected to spend around a week together at a secret resort in Africa before Chelsy returns to her family in her native Zimbabwe for Christmas.

The source added that Chelsy is looking forward to the break from her studies and being able to spend some time with Harry, because although she is enjoying her postgraduate law course at the University of Leeds: “She is [still] a long way from Harry and London’s party scene.”
