The cast of 'The Curious Incident of the Dog in the Night-Time' were "delighted" to have Prince Harry and Meghan Markle attend the show in London.

The 32-year-old royal and the 35-year-old actress - who have been dating for around four months - were spotted out in the British capital's West End on Wednesday (14.12.16) and it was first believed they attended the musical 'Peter Pan Goes Wrong'.

However, it has now been revealed that they went along to an evening performance of the award-winning adaptation of the Mark Haddon novel at the Gielgud Theatre.

The official Twitter page for the theatre production wrote on Twitter: "We were delighted to welcome HRH Prince Harry to last night's performance at the Gielgud Theatre in London's West End. (sic)"

At the the time, a close pal of Harry's said: "Harry has said his privacy is important to him but they are clearly not afraid to be seen in public together.

"They are clearly crazy about each other and have told friends they are very much in love.

"As an actress, Meghan loves the theatre so this was an obvious date to go on."

Meanwhile, Meghan and Harry will reportedly be spending the festive period with their own families with Harry heading to Sandringham and Meghan heading back to Toronto, Canada, to spend the holidays with her loved ones.

And on Monday (12.12.16), the couple surprised staff when they paid a visit to Pines and Needles in Battersea Park, south London, and walked away with a 6ft Nordman fir Christmas tree.

However, it seems it won't be enjoyed by both of them and will just sit at Harry's Nottingham Cottage in Kensington Palace.
