On the official page of the Duke and Duchess of Cambridge, a rare frame was published, which captured Prince William with his heirs.
The picture shows the British Prince William and his three children from Kate Middleton George, Charlotte and Louis. The happy family was photographed while walking outside the family mansion in Norfolk.
The photo was taken the day before, and published on the occasion of a double holiday: on June 21, Prince William celebrates his 38th birthday and celebrates Father's Day. The role of the photographer was performed by Kate Middleton herself, who remained behind the scenes.

By the way, the royal family has a tradition: to publish new pictures on their birthday. Recall that Kate Middleton and Prince William were officially married in 2011, and the future spouses have known each other since studying at the University of St Andrews in Scotland. Over the years of family life, the couple had three children, George, Charlotte and Louis. The couple's eldest son was born in 2013.
