Seven-year-old George, five-year-old Charlotte and two-year old Louis, whose voices are rarely heard in public, asked the 94-year-old broadcaster questions about the natural world in footage recorded at Kensington Palace last month.

The photos were taken in April as the Cambridge family packed up food donations for the needy.

This isn't the first time the Cambridge family has participated in the touching ritual since the coronavirus pandemic began. 

Prince Charles also shared a touching photo with his youngest grandson.

Prince William admitted he was "quite concerned" when his father, Prince Charles, was diagnosed with the novel coronavirus.

William and Kate surprised youngsters with a virtual visit during COVID-19.

"That simply cannot be right in this day and age," William said in his closing remarks.

The Cambridges appear to be done adding to their family, at least according to Middleton.

"Lightning seemed to be crashing around the right wing," a royal reporter tweeted.

Proud parents Kate Middleton and Prince William stepped out of St. Mary's Hospital holding their third baby.
