Queen Mary of Denmark looked typically stylish today as she attended the Freedom Museum in Copenhagen, amid rumours that she dropped out of a planned trip with her husband Prince Frederik.

The Australian-born royal, 52, donned an elegant long trench coat which she tied at the waist as she headed out to the Museum to mark the 75th anniversary of the establishment of the National Guard.

The outing comes amid speculation that Mary may have spent the Easter break away from Prince Frederik as their flag remained raised over their mansion in Amalienborg Castle – meaning at least Frederik, Mary or their son Crown Prince Christian was in attendance.

The family often travel for Easter, with the palace telling Danish publication Her&Nul last week that Queen Margrethe, 83, will act as head of state as the whole family travel out of the country.

However, it seems a last minute change took place, with Mary possibly staying behind in Copenhagen.

This has further heightened rumours over the state of the couple’s marriage, after Frederik was pictured with glamorous Mexican socialite Genoveva Casanova.

Today, Mary attended the event alone.

The Queen paired this with a fashionable wide-brimmed hat and blue leather gloves.

Putting her best fashion foot forward, Mary opted to pair the outfit with heeled tawny leather boots.

The mother-of-two wore her brunette tresses down in a curly blow-dry and opted for glamorous makeup with smoky eye shadow and pink gloss.

Mary’s visit today was also tinged with sadness.

According to Danish newspaper, Billed Bladet, aHome Guard soldier died from a cardiac arrest while on duty the night before Mary’s visit.

Today,  she took to the podium to address military personnel and pay tribute to the fallen soldier.

‘For 75 years, the Home Guard has created security and safety for the Danes.

‘It is a day we want to celebrate, but before I go any further, I would also like to express my deepest sympathies to those bereaved by last night’s tragic death,’ she said.

It’s been a troublesome few years for the Danish royals including ‘affair’ rumours and a rift over title changes, the family has entered a new chapter following the accession of King Frederik X to the throne in January.

As royal fans were sent into a frenzy over the mystery of Mary staying behind, many revisited King Frederik’s night out with Mexican socialite Genoveva Casanova in Madrid last autumn which sparked rumours of an ‘affair’ around the world.

Genoveva was spotted out with King Frederik last November as the pair enjoyed dinner at a flamenco restaurant in Madrid until the early hours of the morning, Spanish magazine Lecturas reported.

Photos of the pair out in the Spanish capital city sparked rumours of an affair, which Genoveva strenuously denied in a legal letter posted on Instagram.

After posting the denial, Genoveva sought solace in San Sebastian where the family of her ex-husband Cayetano Martínez de Irujo owned a property.

Spanish magazine Hola! reported the socialite stayed at the Palace of Arbaizenea, a property once owned by the Duchess of Alba and bequeathed to her son Cayetano Martínez de Irujo. The magazine reported Genoveva heads to San Sebastian any time she needs to ‘disconnect’ from public life.

However last month, after several months off of social media, Genoveva made her return to public life with a new post on her Instagram page – including two selfies with her fluffy pooch.he reality TV star and the King enjoyed included a stroll in a park, going to an art exhibition and a meal while watching flamenco.

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

The pair have only held the title of King and Queen since Queen Margrethe abdicated on 31 December.

This prompted speculation that Queen Margrethe‘s abdication may have been driven to save the marriage of her son and Princess Mary in the wake of the alleged ‘affair’.

Royal commentator Phil Dampier told The Telegraph: ‘It’s possible that the Queen took this action because she would have been terrified of the marriage breaking up and the royal family losing Mary.

‘It would have caused major problems.

‘The Queen has always seen Mary as a tremendous asset.’
