Prince William marked his 43rd birthday today, as celebrations unfolded against the backdrop of the Trooping The Colour event held on June 14, 2025, in London. Looking to continue the royal family’s long-standing tradition of public service, the Duke of Cambridge took part on horseback in the historic ceremonial Pageant.
As the day rolled along, family members began taking to social media to pay tribute to their new favorite holiday. In a poignant birthday tribute posted to Instagram, Prince William’s wife, Kate Middleton, reminisced about their happy childhood days spent together. It opened with an adorable photo of Prince William joined by their family dogs—including their treasured spaniel, Orla.
The birthday caption, adorned with playful paw prints, conveyed a message of “puppy love” and was signed by Kate along with their three children: Prince George, Princess Charlotte, and Prince Louis. This affectionate welcome underscored the tightly woven fabric of the Cambridge family.
Prince George, who is 11 years old, and his siblings—10-year-old Princess Charlotte and 7-year-old Prince Louis—contributed to the celebratory spirit. Only last week, the family was posting Father’s Day pictures. In all of them, Prince William was a delightfully hands-on father. These glimpses into their family life warm him up to the public and further his image as a devoted father.
The Trooping The Colour event is an important celebration within the British royal tradition. It is a celebration that tacitly marks the new monarch’s birthday in perpetuity. Prince William’s participation reflects his active engagement in royal duties while balancing family responsibilities. As he gallops down the streets of London on this well known occasion, he demonstrates just what a novel, young troupe that modern moniker can be.
