Prince William joins a raft of stars at a ceremony in Singapore to reward the five winners of his Earthshot environmental prize. The initiative aims to support the development of solutions to the planet's biggest problems, like climate change, deforestation and waste. The glizy event was co-hosted by British actress Hannah Waddingham and American actor Sterling K. Brown at The Theatre at Mediacorp. Australian actress Cate Blanchett, Hong Kong actor Donnie Yen and South African actress Nomzamo Mbatha were among the stars to walk down the green carpet. IMAGES
