The event is set to take place in London's Leicester Square and honors those who protect Africa's wildlife. The awards are hosted by the Tusk Trust, of which Prince William is a patron.
Earlier in the day, the Duchess of Cambridge took part in a tea party for the winners at Kensington Palace with Prince William, which he referenced in his speech during Thursday evening's event.
"Earlier today, Catherine and I spent some time with the nominees and finalists. Their bravery, single-minded determination, and commitment to African conservation is deeply deeply humbling. So it’s fantastic this year that we’ve been able to see their exceptional work on such an exceptionally big screen!" he said.
"These wonderful films really bring their powerful and inspiring stories to life. And they help to highlight these nominees’ fantastic work to a global audience. So thank you very much to all of tonight’s sponsors for their help in supporting these films, backing the awards, and making this evening possible," William added.
Kate's been keeping a very packed schedule lately. On Monday night, she attended the Royal Variety Performance with Prince William, looking stunning in an Alexander McQueen lace gown. Last week, she opened The Nook Children's Hospice center in Norfolk, England.
She and William have also both participated in multiple Remembrance Day events over the past few weeks.
