Britain's Duchess of Cambridge joked she was "in control for once" when she went abseiling with her husband.
The 33-year-old royal enjoyed some rappelling with Prince William at Towers Residential Outdoor Education Centre in Capel Curig, Wales and was put in charge of his safety rope.
He asked her nervously: "Are you holding me?"
To which she replied through a laugh: "I've got you. I'm quite enjoying this actually. For once I'm in control."
The Duchess then took a turn herself, insisting she and William aren't "competitive".
She added: "This is the 'agh' moment. Not that we're competitive but if he does that, then I'm having to do it too!"
Instructor Phil Blain was pleased with the Duchess' rappelling skills.
He shared: "If that was Kate's first abseil she did fantastic. And that was probably the first time she's held the life of the heir to the throne - and her husband - in her hands."
Meanwhile, during their tour of Wales, the royal couple revealed their son Prince George, two, has taken a liking to helicopters.
Pauline Hallett, who was volunteering with the Ogwen Mountain Rescue, said: "Catherine then said how much George loved them [helicopters].
"He knows all the different colours and asks her about all the parts. She laughed and said she tells George to ask Daddy as she has no idea."
