Actress Catherine O'Hara was joined by her husband Bo Welch at the awards. She wore a fun printed suit.

"Repairing our planet is one of the most important things we can do in our lifetimes. The passion and ambition of this year’s Earthshot Finalists is much needed in a world of such turmoil, and I am truly honoured to play a role in helping them share their work with the world," O'Hara shared ahead of the ceremony.

Sisters Chloe and Halle looked gorgeous in ballgowns. Their green and black dresses worked perfectly with the backdrops.

Actress Shailene Woodley opted for a lace black dress.

Co-presenter Clara Amfo stunned in a black dress. It's her second time hosting the ceremony. She shared before the ceremony, "I was so inspired by last year's winners, and I’m looking forward to celebrating and sharing the incredible work of the 2022 finalists with the world."

Beckham was a surprise addition to the Earthshot line-up, and he kept things classic in a black tuxedo.

Singer Ellie Goulding looked ethereal in a white gown. She performed at the wedding of Prince William and Kate Middleton in 2011.

Singer-songwriter Annie Lenox kept things casual in a red scarf, velvet blazer, and green pinstripe pants.

Actor Rami Malek, who is presenting an award this evening, looked handsome in a tux. "The fifteen finalists of this year's Earthshot Prize are deeply inspiring. They are dedicating their lives to building solutions that will repair our planet," he shared ahead of the ceremony.

It wasn't just celebrities on the green carpet; U.S. politicians—like Senator Mitt Romney and his wife, Ann—were also in attendance this evening.
