Queen Mary of Denmark looked typically chic as she made a special appearance at a university in Copenhagen yesterday.
The 52-year-old royal hosted the Maratonsang event at Vartov College in the centre of the city.
Maratonsang is an annual tradition which held on the longest day of the year.
It sees hundreds of people gather in the courtyard of Vartov College to sing together, from early morning to late evening.
The Australian-born Queen appeared delighted to be hosting the event, and was photographed smiling and waving at the assembled crowds.

Mary arrived at Vartov College looking stylish as always, in an orange maxi dress feating a white floral print.
The long-sleeved frock had long sleeve, a round neckline, and a white seam which cinched in the waist.
Her frock was created by Australian sisters Nicky and Simone Zimmermann's eponymous brand which they founded in Sydney in 1991.
She paired the dress with pointed, heeled Mary Jane style pumps, which had two thin straps across her foot, and were the same hue as her dress.
Mother-of-four Mary styled her shiny chestnut locks into a half-up, half-down do, which allowed her to show off a pair of dangly green and orange statement earrings, while still leaving some of her tresses flowing loosely down her back in gentle waves.
When it came to her make-up, the popular royal looked radiant, with fresh, dewy skin and peach blush.
She paired her base with a light smokey eye, using brown shadow for definition, and a natural pink lip.
During the event, Queen Mary led part of the service with several songs, which had a Denmark theme.

Earlier this month, Queen Mary and her husband King Frederik X made a joint engagement as they marked the 175th anniversary of the Constitution in Copenhagen.
Mary and her husband put on a united front, appearing in high spirits despite having been plagued with rumours of marital struggles since the King was pictured enjoying an evening out in Madrid with Mexican socialite Genoveva Casanova last year.
The publication of the photos resulted in Genoveva, 47, issuing a statement denying a romantic relationship between herself and the royal and slamming the 'malicious' rumours.
That appearance came after King Frederik and Queen Mary appeared on the Amalienborg Palace balcony for the monarch's birthday.
The father-of-four celebrated his first birthday since he ascended the throne on 26 May and greeted crowds of royal fans who had gathered outside the residence.
Frederik and Mary were joined on the balcony by their four children Crown Prince Christian, 18, Princess Isabella, 17, and twins Prince Vincent and Princess Josephine, 13.

The family-of-six were joined on the balcony by Queen Margrethe, 84, who abdicated in January following a 52-year reign. The mother-of-two looked glamorous in a bright pink midi dress with short sleeves.
Earlier that day, the Danish Royal Household released a new portrait of King Frederik to mark the monarch's 56th birthday.
Australian-born Mary and Frederik's 23-year romance was often dubbed a 'real-life fairytale' after they met in a Sydney pub.
But pictures emerged of the monarch having an evening out with Mexican socialite Genoveva Casanova - the former daughter-in-law of the billionaire Duchess of Alba - in November last year.
The pair were seen walking through Madrid before heading to her apartment building, changing clothes and heading out again for the evening.
