Prince Harry and Meghan Markle were snapped sharing a touchingly intimate moment during a visit to Cardiff Castle today.
Harry, 33, was caught on camera as he whispered a few words in his fiancée's ear, eliciting a coy smile in response.
The couple, who were delayed in their visit due to a problem with the trains, greeted well-wishers outside the castle before making their way inside for a 90-minute stay.
For the occasion, Meghan, 36, chose a pair of black skinny jeans from Welsh brand Hiut Denim, which provided the perfect touch of diplomatic dressing, as did an off-the-shoulder top in Prince of Wales check - a nod to her future father-in-law.

Dating back some 2,000 years, the castle is on the site of what was once a Roman fort.
It passed through the hands of many noble families until 1766, when it was given by marriage to the Bute family, responsible for turning Cardiff into the world’s greatest coal exporting port.
John, the 3rd Marquess of Bute, was by the 1860s reputed to be the richest man in the world.
The castle was eventually given as a gift to the city of Cardiff by the Bute family in 1947.

Harry and Meghan's official engagement today did not go completely smoothly, as a train delay meant they were late.
The couple left Paddington Station on time at 11.15am on route for Cardiff.
But delays to the GWR train mean they will not arrive into the Welsh capital until well after 2pm - making them at least half an hour late for their third public engagement as a couple.
Besotted Harry, 33, has made a promise to his bride-to-be to undertake visits across the UK before their wedding, to give the US-born actress a chance to see the country she will come to call home and meet its people.
The first fan waiting to meet them was Jenna Quilter, 18, from, Cregiau, who arrived at 6.30am.

She told the BBC: ‘It’s fascinating that she’s not the typical person you’d expect to become a future duchess and it’s just really interesting to see the public reaction to her,’ she told the BBC.
She added: ‘I’m a big fan of the royals. Mainly the Duchess of Cambridge but I adore Prince Harry.
‘I think Harry and Meghan represent a more modern society and it keeps some of the British traditions alive. I’ve got some roses for Meghan too.’
Abbie Smith, visiting from Louisiana, added: ‘In America this is like a fairytale.
'I think it’s really cool that she’s from the States and gets to experience the Royal lifestyle as well.’
