Royal Family LIVE: King Charles and Queen Camilla mark late Queen's birthday with memorial plans and palace reception

HELLO!'s royal editor, Emily Nash, is at the British Museum for today's event, and members of the royal family have started arriving. First up were the Duke and Duchess of Gloucester, with the Duchess looking radiant in a pink outfit.

"The Prince and Princess of Wales have paid tribute to the late Queen with a selection of images of the late monarch's life. Some of the photos selected feature the late Queen with both William and Kate, alongside a stunning black-and-white portrait of when Queen Elizabeth II was a young adult.

In the caption, they wrote: "Remembering Her Majesty Queen Elizabeth II on the 100th anniversary of her birth. Inspiring generations through a lifetime of duty."

Although Mother's Day has passed us by this year in the UK, over in the US, the special celebration is fast approaching. Meghan has unveiled some new products ahead of the date, including candles that are named after her own children's birthdates. In the post, she also included a subtle tribute to her brood with a necklace. See if you can spot it in the image!

Prince Albert has kicked off his state visit to Greece, meeting with the Prime Minister, Kyriákos Mitsotákis. During his trip, which ends on Wednesday, the royal will discuss bilateral relations between the two countries, as well as major international issues of mutual interest. However, one of the highlights of the trip will see Albert presented with the Medal of the City of Athens, in recognition of his commitment to international dialogue and his environmental initiatives.

It's not just the British royals who are marking major events today, as Denmark is also celebrating the 19th birthday of Princess Isabella, the second child of King Frederik and Queen Mary. To mark the occasion, which fell shortly after the confirmation of Prince Vincent and Princess Josephine, the Danish Palace shared several portraits of the teenage royal.

Marking his late mother's centenary, King Charles released a special video message marking the occasion. "Much about the times we now live in I suspect may have troubled her deeply, but I take heart from her belief that goodness will always prevail and that a brighter dawn is never far from the horizon," he said. 

"For as a young Princess Elizabeth put it in her first ever public broadcast, aged just 14, we can each play our part 'to make the world of tomorrow a better and happier place'. It is a belief which I share, with all my heart."

The late Queen is already being honoured with several touching social media messages. The Royal Family posted: "Remembering Her Majesty Queen Elizabeth II, 1926 – 2022," alongside several images of Her Late Majesty throughout her life.

The UK Ministry of Defence also said: "As we mark the centenary of her birth, we remember today the life of Queen Elizabeth II, and her unwavering service and dedication to our Armed Forces."

In their post, the late Queen was pictured alongside the late Duke of Edinburgh as they rode in a royal carriage.

So, if you're not aware of what the plans are for today's big events, here's what you need to know.

King Charles and Queen Camilla are due to be at the British Museum to observe the designs for the upcoming Queen Elizabeth Memorial. They will be joined by other members of the royal family and the Prime Minister, Keir Starmer. Meanwhile, Princess Anne will officially open The Queen Elizabeth II Garden in The Regent's Park.

These will take place ahead of a reception held at Buckingham Palace to honour the late Queen's centenary. There will be one absence, as Prince Edward will be in Truro at the Hall for Cornwall.

And away from the British royals, Denmark's Princess Isabella is celebrating her 19th birthday.

Good morning all! It's a big royal day as today marks what would have been the late Queen's 100th birthday. Major royal events are scheduled to be held throughout the day, and Best Quality Designer Handbag will be bringing you all of the information and best pictures as it happens!
