Prince William received some unexpected advice about aging during an event commemorating what would have been Queen Elizabeth’s 100th birthday.

On Tuesday, April 21, the Prince of Wales and other members of the royal family honored the late Queen Elizabeth’s legacy with a reception at Buckingham Palace. Hosted by King Charles and Queen Camilla, guests included royals like Kate Middleton, Princess Anne, Prince Edward and Sophie (the Duke and Duchess of Edinburgh), as well as citizens celebrating their 100th birthdays.

According to Hello! magazine, William, 43, shared a humorous moment with one of the centenarians, Joan Illingworth.

The Prince joked that she looked much younger than her 100 years, saying, “I can’t believe you are 100! Do we need to call security, have you snuck in?”

After their conversation, Illingworth said, “The Prince of Wales said I looked well for my age and asked what was my secret.” According to Hello!, she revealed that eating clotted cream fudge and Liquorice allsorts — both popular sweet British confections — was her secret to staying youthful.

At the reception, the invited centenarians dug into a birthday cake, which was decorated with the number “100” in gold. A band performed “Happy Birthday” and King Charles and Queen Camilla personally presented their guests with 100th birthday cards. (Centenary cards are free messages from the King and Queen available to all British nationals. Messages are sent for 100th birthdays, 105th birthdays and each year after 105.)

The royal family also used the occasion to take a rare group photo featuring all the working members.

The reception was only one of the many royal events marking Queen Elizabeth’s centenary. (The late monarch died in 2022 at age 96; she would’ve turned 100 on April 21.)

On Monday, April 20, King Charles, 77, and Queen Camilla, 78, stepped out to visit the new exhibition Queen Elizabeth II: Her Life in Style, which is being held at the King’s Gallery at Buckingham Palace. The exhibit features over 300 items from the Queen’s wardrobe, with over half of the exhibition pieces on display for the first time.

The King’s sister, Princess Anne, 75, marked the occasion by officially opening The Queen Elizabeth II Garden in Regent’s Park, London on April 21. King Charles and Queen Camilla also attended the British Museum on the same day, to view the design recommendations for an upcoming memorial in Queen Elizabeth’s honor.
