Cressida Bonas is to co-host a royal engagement with Prince Harry.
The 25-year-old blonde has officially been recognised as the prince's girlfriend as she has been invited to host the royal dinner - in honour of the war veterans who completed a South Pole trek with Harry last year - at St James's Palace this week.
A source told the Daily Express newspaper: "Harry and his mates went through thick and thin together, so the dinner party will be a really relaxed and jovial affair.
"But there is no doubt that it will be a royal banquet, albeit a private one."
The dinner will see Harry reunite with his fellow trekkers, with whom he walked to the South Pole in treacherous weather conditions in December.
The 29-year-old royal took part in the trek for the Walking with the Wounded charity - which he is a patron of - and was joined by numerous war veterans who returned from duty with life-changing injuries, such as lost limbs.
Harry and Cressida were recently seen being affectionate with one another at the We Day charity event in London.
The couple - who have been dating for two years - were also spotted enjoying a rugby game at Twickenham Stadium.
