It is understood the Queen is planning to throw a joint 40th birthday party for her granddaughter and wife Kate Middleton after she was forced to cancel her celebrations due to a spike in COVID-19 cases earlier this year.
The couple were given the green light to throw a party at Queen’s Windsor Castle or Sandringham Estate this summer to “celebrate their historic anniversary in style”, a royal source told The Mirror.
Prince Charles was the first to wish his son a happy birthday.
“Happy 40th birthday to the Duke of Cambridge,” the Prince of Wales and Duchess of Cornwall wrote on Twitter alongside photos of the Duke over the years.
One of the photos includes a sweet snap of the father and son duo in their English country gear.
Charles looked very mesmerized next to William, who was hugging his father.
The Queen also shared some photos of the Duke as he wished his grandson a happy birthday.
“Happy Birthday to the Duke of Cambridge!” The Royal Family tweeted.
“When the second heir to the throne turns 40, learn more about His Majesty.”
The Royal Family’s social media pages list Prince William’s highlights and accomplishments throughout the years, including his graduation from St Andrew’s University in June 2005 with a 2:1 Master of Arts (Honours) in Geography.
Upon graduation, the Duke of Cambridge completed a 44-week training course at the Royal Military Academy Sandhurst as an Officer Cadet before starting training as a Search and Rescue pilot in 2009.
She now undertakes a number of charity activities and projects, with a particular focus on the environment, youth and mental health.
The Duke of Cambridge has followed in the footsteps of his late mother Princess Diana by supporting a number of homeless charities including The Big Issue magazine, which offers job opportunities to poor people.
Earlier this month, Duke was praised for his “silent demeanor” after he was seen taking to the streets of London selling magazines.
