Duchess Kate and Prince William step out to their first joint engagement this fall – with Sir David Attenborough!

Happy Thursday! In what's been an absolutely *packed* week of royal events, fans were treated to an additional amazing appearance when <strong><a href="/tags/0/prince-william">Prince William</a></strong> and <Strong><a href="/tags/0/kate-middleton">Duchess Kate</a></strong> met up with Sir <strong><a href="/tags/0/david-attenborough">David Attenborough</a></strong> for a special ceremony in Birkenhead. <p>The <i>RRS David Attenborough</i>, a scientific boat named after the legendary naturalist and documentary filmmaker, was officially named in a celebration on Sept. 26. <p><strong>Click through the gallery (or keep reading if you're on mobile) to see some of the best photos from the fun event!</strong> <p>Photo: &copy; Anthony Devlin/Getty Images
Before we get to the day's events, we need to talk about Kate's gorgeous coat! The Duchess of Cambridge arrived in a beautiful blue <strong><a href="/tags/0/alexander-mcqueen">Alexander McQueen</a></strong> utility coat. <p>We first saw this coat in April 2014. She wore it again two months later and brought it out more than two years after in the fall of 2016. And here it is again! Kate loves to re-wear the most beloved items from her wardrobe and it makes her incredibly relatable! <p>The 37-year-old was also carrying a 1781 Pochette style <Strong><A href="/tags/0/asprey">Asprey</a></strong> clutch. <p>Photo: &copy; Anthony Devlin/Getty Images
There was a massive crowd out to see the naming ceremony for the <i>RRS Sir David Attenborough</i>, which will be operated by the British Antarctic Survey and will conduct important scientific research about the Earth's poles. <p>Photo: &copy; Peter Byrne - WPA Pool/Getty Images

The duchess was very keen to say hello to the wellwishers and royal fans who had come out for the event. <p>Photo: &copy; Anthony Devlin/Getty Images
David did the same! He is considered a national treasure in the UK, though he doesn't like the term, but given the incredible career he's had and the amount he's contributed to science and documenting the Earth's natural history, it's no surprise people came out in droves to see him! <p>Photo: &copy; Anthony Devlin/Getty Images
William, Kate and David went right up on the ship's top deck for a special photo op. <p>Photo: &copy; Peter Byrne - WPA Pool/Getty Images
Then it was time for some speeches! They had a blast while introducing David. <p>Photo: &copy; Anthony Devlin/Getty Images
This is William's third engagement with David this year. He interviewed the filmmaker and historian <a href="https://ca.hellomagazine.com/royalty/02019012249492/prince-william-interviews-sir-david-attenborough/"><strong>at the World Economic Forum</a></strong> in Davos in January, and also attended the premiere of David's <strong><a href="/tags/0/netflix">Netflix</a></strong> documentary series <i>Planet Earth</i> in April. <p>This was Kate's first event with him this year, and the two seemed to really get along quite well! <p>Photo: &copy; Anthony Devlin/Getty Images
David made a special speech at the event. Before the cceremony, he told BBC Radio 4 that it took a "long time for the penny to drop" on climate change, but real action is starting to happen. He said young people such as Sweden's <strong><a href="/tags/0/greta-thunberg">Greta Thunberg</a></strong> were driving the majority of the action. <p>Photo: &copy; Anthony Devlin/Getty Images
