Meghan Markle joined husband Prince Harry on a trip to the Netherlands for the Invictus Games earlier this year.
And it has emerged that while in the country, Meghan carried out a secret visit to take on a role as a guest coach for a girls’ entrepreneurship course.
Meghan visited the Project Fearless initiative in Amsterdam in April but the trip has only just been made public.
Photos shared by the Dutch non-profit organisation on Monday showed Meghan hugging a delighted young participant, and also cheering with her hand in the air in a team photo with the teenagers.

The duchess said, in a statement released by Archewell: “Safe, supportive spaces like Project Fearless allow girls the opportunity to express themselves, build each other up, gain resilience and tackle new challenges.”
Project Fearless aims to give girls and non-binary youngsters aged nine to 14 the tools to succeed through after-school courses, including, among others, on climate science, skateboarding, kick-boxing and entrepreneurship.

It announced the duchess’ visit to mark its third birthday.
It described how former actress Meghan helped the students with their business pitches and “enthusiastically” took part in a group exercise on facing fears.
“Earlier this year, Meghan, the Duchess of Sussex, joined our first entrepreneurship course as a guest coach,” it said.
“During her visit, she gave the girls inspiring and encouraging feedback on their sustainable business pitches, and enthusiastically joined in with a group exercise on facing fears.”
Merida Miller, founder of Project Fearless, said: “The duchess’ visit was a brilliant way to celebrate the impact Project Fearless has made over the last three years, introducing the girls to an accessible role model who is making a difference and using her voice.”
The visit took place before Meghan and Harry jetted to the UK with their two children Archie and Lilibet for the Queen's Platinum Jubilee celebrations.
The couple only attended one of the Jubilee events publicly and weren't present at the rest of them.
And royal expert and author Tina Brown has claimed it must have been t ough for them to watch on from the sidelines.
She told ITV's Lorraine: ""It was great that they were able to introduce Lillibet to the Queen. I'm sure that everyone wanted that to happen. But it clearly was uncomfortable that they were there but not really present. It was awkward."
