Prince Harry takes his girlfriend Meghan Markle on private tour of Natural History Museum here.
The date is said to have taken place on Sunday after the museum closed to the public, reported The Telegraph.
"Meg had always wanted to go so Harry arranged a private visit. It's quite romantic after dark as all the exhibits, including the dinosaurs, are all still lit up," a source said.
The couple have been together since last summer. They were seen earlier this month at a friend's wedding in Jamaica.
