Sir David Attenborough attended a private screening of his new documentary, A Life On Our Planet, at Kensington Palace, with Prince William, Kate Middleton, Prince George, Princess Charlotte and Prince Louis for company.
The naturalist and documentary legend, 94, had a huge smile on his face as he mingled with the young royals - and so did Prince George after he gifted him a fossilised giant tooth from an extinct shark.
The young prince, seven, looked fascinated by the tooth, which was from a carcharocles megalodon.
Meanwhile, Prince Louis, two, and Princess Charlotte, five, stood nearby and fan-girled massively (who can blame them?!).

We so wish we were a fly on the wall during this meet-up!
The private screening comes after Sir David and Prince William have got to know each other through their public campaigning for environmental issues.
The film viewing - which saw Prince William and Sir David take to personalised chairs to watch - was held in Kensington Palace grounds, with strict social distancing in place.
Produced by award-winning wildlife filmmakers Silverback Films and global environmental organisation WWF, A Life On Our Planet will chronicle David's extraordinary life, focusing in detail on "the man who has seen more of the natural world than any other."

But, of course, it will also look in great detail at the issue closest to the documentarian's heart. The biggest issue of our time: saving the natural world.
Described as "honest, revealing and urgent", the film reportedly gives "a powerful, first-hand account of humanity's impact on nature and a message of hope for future generations".
The movie has understandably had a lot of hype. In fact, it even prompted Sir David to make an Instagram account on Thursday (24 September) so he could interact with fans, and update them on the doc ahead of its release.

The movie was originally due to receive its world premiere at the Royal Albert Hall on 16th April, accompanied by a live Q&A with the great man himself, ahead of a wider release in cinemas - but it became a casualty of the coronavirus pandemic, causing delays.
It will now have a limited release in some cinemas across the UK on Monday 28th September, before landing on Netflix on Sunday 4th October.
After the screening, Sir David stopped for a catch up with the Duke and Duchess and their three children.

It comes after he was interviewed by Prince William at the World Economic Forum in Davos, Switzerland last year, and worked with him on a number of environmental initiatives, including the Earthshot Prize.
