Crown Princess Mary looked 'frosty and judgemental' during first engagement she's carried out alone with husband Prince Frederik since photos that triggered an 'affair' scandal

Crown Princess Mary and Crown Prince Frederik looked 'tense' during their first engagement as a couple since photos of his night out with a Mexican socialite emerged, a body language expert has claimed.

The future King and Queen of Denmark have carried out engagements with other family members, as well as the King and Queen of Spain, since the scandal broke.   

However, pictures of the royals with Denmark's climate ambassador Tomas Anker Christensen at Amalienborg Palace, Copenhagen, were shared on Instagram on Thursday.

The meeting was their first solo engagement as a couple, without other members of the royal family, since the scandal of his night in Madrid with Genoveva Casanova. 

And body language expert Judi James claimed Mary's rigid stance suggests there is 'tension', while her pursed lips 'hint at judgemental thinking'. 

As for Frederik, 55, Judi said his crossed arms add to the 'air of coolness' in the room, even though he looked more relaxed.

The pair met with Christensen to discuss Denmark's climate efforts ahead of COP28 in Dubai in December.

For the meeting, Mary, 51, donned a light pink blouse and wide leg black trousers, while Frederik sported a navy suit with a light blue shirt underneath. 

But while the colour palettes were subtle, the same could not be said for the change in Mary's body language since rumours of the scandal emerged - which Judy called 'dramatic'.

'Princess Mary’s body language before all the rumours of a scandal tended to feature a very soft, warm and playful facial expression when she was with her husband, Crown Prince Frederik, which makes this subtle switch to a frostier look seem dramatic,' Judi said. 

She said that sitting side by side, Mary and Frederik show two 'very contrasting' body language states. 

'Mary looks formal and tense,' Judi claimed. 'Her slightly raised chin, tilted head and primly pursed lips hint at judgemental thinking, with her eyes on Christensen.'

And Frederik appears to be either consciously or subconsciously trying to show off his wedding ring, Judi suggested, adding that he appears to be 'feigning relaxation'.

'His crossed arms appear odd, adding to the air of coolness in the room,' Judi said. 

'When we fold our arms we do so in one way only. Swapping the upper arm position with the lower is almost impossibly awkward to do. With this gesture which is more like a self-hug then, Frederick’s trait of placing his left hand on his own bicep looks suspiciously like a conscious or unconscious desire to show off his wedding ring here rather than part of an actual arm-folding.'

She added: 'He also has creases of what look like tension or anxiety between his brows.'

Of the staircase image, Judi said Mary's pose 'suggests tension', as her feet are tight together and her shoulders and smile look more 'rigid' than usual. 

The expert said the line-up for the picture 'lacks symmetry', as Mary stands closer to Christensen while Frederik is rather far from him. 

And people on social media picked up on the 'frostiness', with one person commenting: 'They don't look sparkling together as they used to.' 

'Looks chilly…' said another, while a third wrote: 'The elephant in the room ... oh dear.' 

It comes amid drama for the Danish monarchy after Frederik was pictured on a night out with Mexican socialite Genoveva out and about on the streets of Madrid on 25 October, as reported by Spanish magazine Lecturas.

In the photos, which are taken throughout the day and into the evening, the pair enjoy a stroll through the park, before getting into a change of clothes and heading out again for the evening.

After it was reported that the duo had enjoyed an evening out in the Spanish capital without Frederik's wife of 19 years, Crown Princess Mary, Genoveva, 47, issued a statement denying any kind of romantic relationship between herself and the future Danish King. 

In a legal letter posted on Instagram, she slammed the 'malicious' rumours suggesting the pair were romantically involved.
