See Prince William and Kate in Behind-the-Scenes Photos from Their Earthshot Prize Awards

Prince William and Catherine, Princess of Wales, just gave us all a lovely glimpse into their romance by sharing a series of private new photos from their Earthshot Prize Awards.

"Celebrating brilliant solutions and the inspiring people behind them!" they captioned a Twitter post with the behind-the-scenes snaps.

In one shot, the prince and princess are seen gazing lovingly at one another and smiling while dressed to the nines: William in a black suit, crisp white shirt, and bow tie; and Kate in a long-sleeved mint green belted dress and Princess Diana's emerald choker with matching earrings.

Another photo shows Kate smiling proudly at her husband and clapping for him as he speaks to a large crowd. And other separate images show William and Kate alone in their gala ensembles.

Prince William and Kate visited Boston last week to host their second annual Earthshot Prize Awards, a ceremony William started to recognize innovators for their achievements in tackling the world's biggest environmental problems.

The event this year brought along a bevy of talent. Billie Eilish, FINNEAS, Chloe x Halle, Annie Lennox, and Ellie Goulding were among the evening's performers. Meanwhile, hosts and presenters included broadcasters Clara Amfo and Sir David Attenborough, as well as actors Catherine O'Hara, Rami Malek, Shailene Woodley, and Daniel Dae Kim.

Kate and William's three-day trip marked the first time they visited the United States since 2014. See all of Kate's elegant looks from their engagements in Massachusetts here.
