It's the clearest indication yet their romance is firmly back on track and moving up a gear: Prince Harry has reportedly moved in with Chelsy Davy.
The pretty South African has apparently given the third-in-line keys to her £1.5 million Belgrave home, for use at the weekends.
Harry stays at the three-bedroom flat when he is not at Middle Wallop in Hampshire, where he is training to be an Army Air Corps helicopter pilot during the week.
Sources told the Daily Mail that the prince felt Clarence House, where he has his own living quarters with Prince William was "too cramped", especially when Kate Middleton also comes to stay.
Harry and Chelsy reunited last summer after a five-month break in their five-year romance.
They spent New Year's eve together in Mauritius, but are currently apart – Chelsy is on holiday in South Africa at the moment.
The sweethearts are expected to meet up in Cape Town in June, during the World Cup.
Harry recently posted a message on the 24-year-old's Facebook page saying: "Cape Town... can't wait. Miss you loads"
