Prince Harry and his girlfriend Meghan Markle have reportedly visited the Natural History Museum for a private tour.
The date is said to have taken place on Sunday after the museum closed to the public.
A source told the Sun newspaper: “It’s quite romantic after dark as all the exhibits, including the dinosaurs, are all still lit up.
“And of course, they had it to themselves.”
Ms Markle is said to have arrived in London late last week.
The couple have been together since last summer. They were seen earlier this month at a friend's wedding in Jamaica.
The Prince's nephew, Prince George, is known to be a fan of the Natural History Museum.
The Duchess of Cambridge, is a patron of the museum and has spoken of her son's love of dinosaurs.
She said last year: "George loves the T Rex because it's the noisiest and the scariest."
The Natural History Museum is in South Kensington, not far from Kensington Palace, where Prince Harry has a cottage.
The Duke and Duchess are intending to return to Kensington Palace in the autumn, as they prepare to spend more time in London.
