Prince Harry and his actress girlfriend Meghan Markle were spotted attending a West End play together.
Harry booked last minute tickets for comedy Peter Pan Goes Wrong at the Apollo Theatre in London on Wednesday night, according to The Sun.
On Tuesday, they were seen buying a tree in the capital as they spent time together ahead of the Christmas holidays.
The latest sighting comes as the Duchess of Cornwall hosted her annual festive gathering at Clarence House.
Camilla was joined by children and families supported by Helen & Douglas House and Roald Dahl's Marvellous Children's Charity.
Each year, the Duchess invites youngsters to help her decorate the fir tree and join her for lunch, serving sausages and mash, and an array of treats.
Helen & Douglas House is based in Oxford and provides respite support and end-of-life care, while Roald Dahl's Marvellous Children's Charity helps children with serious illnesses.
Camilla, holding a large heart-shaped garland, took instructions from one little girl who was busy organising the placing of the red and white decorations.
The Duchess asked: "Do you want me to put it there? Are you sure it's there?"
Clarence House tweeted: "The finishing touches have been made to the @ClarenceHouse Christmas tree and it looks beautiful!"
A long table was in place for lunch, covered with a white linen cloth, and ready with jugs of orange and blackcurrant juice and plates of heart-shaped iced cookies and chocolate biscuits.
It is the eighth time children from Helen & Douglas House, of which Camilla is patron, have visited Clarence House to take part in the Duchess's yuletide tradition.
The Duchess told her guests: "It's always a joy having you all and I hope everyone enjoys the bangers and mash."
Some of the youngsters including Blake Morris and Millie Fagan-Barnes, both seven, tried on a bearskin hat belonging to Camilla's equerry, Captain Matthew Wright of the Welsh Guards, who was in ceremonial dress.
As Millie peeked out from under the large headwear, the Duchess remarked: "She's disappearing... was it hot in there?"
Her mother Tracey Barnes said of Millie, who has cerebral palsy and epilepsy: "Millie has been ill earlier this year. It's lovely to be back like this. It's been a fantastic day. She's been so looking forward to it."
