Yesterday, she appeared relaxed as she gave a speech to open the centre in Denmark, before chatting with members of staff who are working at the organisation.

The Danish National Center for Grief offers free counseling to anyone who has lost a parent, a sibling, a child or spouse, or people who are relatives of people suffering from severe physical illness.

The center also offers a helpline, called Griefline.

She was seen soaking up the sun on the Spanish island with her husband Prince Frederik on Wednesday.

Mary took a refreshing dip in the ocean with Frederik and flaunted her stunning figure in the one-piece green swimsuit by Danish brand Copenhagen Cartel.

The 51-year-old wore the same one-piece on Sydney's Palm Beach in December 2022.

Mary and Frederik were spotted taking a break from the kids and their luxury yacht when they took a dinghy to a beach with another couple.

The loved-up pair look relaxed as they swam, chatted and laughed together in the turquoise water.

Once on shore, Mary covered up with a bright yellow button-up shirt and khaki shorts while Frederik wore a blue T-shirt over his board shorts.

The princess protected herself from the sun with a white Panama hat and Wayfarer-style sunglasses.

Mary didn't skip the accessories with gold layered necklaces and a $256 Jerome Dreyfuss leather phone bag.

Her sporty swimsuit features a chic square neckline, adjustable skinny straps and seam detailing around the top.

It also includes a two-layer fabric for ultimate support and fit, is UPF 50+ and is made with soft and breathable fabric.

The family's holiday comes after Princess Mary's eldest son Prince Christian shocked royal fans with a bold announcement ahead of his 18th birthday.

The young prince, who will celebrate his 18th on October 15, will break protocol by forgoing his royal allowance to instead focus on his education.

While the future Danish King is entitled to government funding once he reaches adulthood, he will not accept payments and become a full-time royal until he is 21 years of age.

A statement to the Royal House's Instagram page said: 'Prince Christian's main priority in the coming year will be the completion of the Prince's upper secondary education.'

'It has thus been agreed with the Ministry of State that support in the Danish Parliament for a law on annual pension will only be sought when the prince turns 21 or by a possible change of the throne, if it takes place before.'

The statement concluded by saying Christian will refrain from the spotlight but one day return to making public appearances in an official capacity.

'Only after this is the expectation that His Royal Highness will participate to a greater extent in official contexts,' it said.

'However, it depends on where the Prince is at this point in his education. Until then, just like today, Prince Christian will only participate in official contexts to a limited extent.'

Although he has made many public appearances alongside his parents and siblings Christian is not yet a full-time working royal.
