Kate Middleton and Prince William were caught packing on some PDA when they attended the first Earthshot Prize Awards ceremony.

The Duke and Duchess of Cambridge shared behind-the-scenes photos from the glamorous event Sunday. The black and white pictures they shared on Instagram showed the side of Middleton and Prince William that many didn't notice at the ceremony.

In the first picture, Middleton was all smiles while her husband leaned and looked back at her as they walked through a curtain. In the second shot, the duke was standing alone backstage.

The third photo captured the netizens' attention because the royal couple rarely packs on the PDA. However, in the picture, the duchess was seen smiling sweetly at her husband while resting one hand on his back. They seemed to be engrossed with what they were talking about because Prince William was also looking at his wife intently.

"Behind the scenes at the first ever @EarthshotPrize Awards," the couple wrote in the caption.

The post received positive comments from the royal fans who were very happy to see the pictures. One compared it to a scene from a fairytale. A second user said it was an "absolutely magical event" with the future king and queen. Another fan wrote, "Their romance is really regal."

Prince William and Middleton's appearance at the event received compliments from the netizens. Many were particularly impressed with Middleton who recycled her 2011 lilac gown by Alexander McQueen.

One said the duchess dressed appropriately because she didn't go for a head-turning gown, knowing that it was her husband's big night. Another user said Middleton's habit of wearing the same dresses again was a great example for everyone to do the same. A third fan was also jealous of the duchess because her dress was still a perfect fit for her after 10 years and despite having three kids.

Prince William rocked a green velvet tuxedo at the event and the majority gave it a thumbs up. Some even said they were rooting for the Duke of Cambridge to be the next James Bond. It can be noted that Daniel Craig sported a deep fuchsia pink velvet tuxedo at the "No Time to Die" premiere last month.

Meanwhile, Prince William made a huge announcement at the event. The duke said Earthshot Prize will be heading to the United States, where his brother Prince Harry and sister-in-law Meghan Markle currently live.
