Duchess Kate and Prince William turn heads with rare PDA -- watch the cute moment!

Prince Harry and Meghan Markle may have inspired a major change in Duchess Kate and Prince William's relationship. 

During a visit to BBC Studios last week, Kate strayed from royal tradition as she showed some PDA with William. The 35-year-old royal sweetly put a hand on her husband's knee in the middle of an interview where they discussed the Blue Peter honor they received for their campaign work around mental health issues affecting children. They followed in the footsteps of Queen Elizabeth, who was awarded the program's highest award during her Golden Jubilee year in 2002.

Kate Middleton & Prince William coordinating outfits in summer 2017
July 22: How lovely is Kate's lavender look?! Rather than try to perfectly match the unique color, Will nailed it in a complementary tie in the same color family.
July 21: Later in the day, Prince George and Princess Charlotte joined Mum & Dad in pastel tones of the same color scheme!
July 19: Pretty uncommon to see the Duchess showing her shoulders! Kate mixed things up in this flowing red maxi, and Will's coordination was just right with a red tie and not-too-dark navy suit.
July 20: Okay, their outfits totally clashed on this day, but they looked like a cute husband-wife team in these white lab coats.
July 20: Casual -- but still couple-y! The royal pair both chose shades of blue before they hopped into boats for a rowing race.
July 19: Too stunning for words. The Duke and Duchess were picture-perfect in blue. Kate layered a flared coat dress over a tight lace number, and Will paired a dark navy suit with an impeccably-selected blue tie.
July 19: Oh, did we mention that the littlest royals coordinated, too? Prince George and Princess Charlotte were mini-mes of their parents in lighter shades of blue.
July 18: It's tricky to pair with a pattern, but kudos to Will for taking a risk with his dotted tie. It's just playful enough to work with Kate's floral number -- and it appropriately pulls out just the right shade of greyish green.
July 17: We love that Will's outfit doesn't compete with Kate's. In a crisp white shirt and dark suit, he lets Kate's all-white ensemble does all the talking. But there was still some serious coordinating happening today...
July 17: ...with the whole family! Will's red tie suddenly makes much more sense alongside the kiddos, who also wore navy, white and red.

"That's very touching. Thank you very, very much," said William as he received his badge from presenters Radzi Chiny and Lindsey Russell. "Wow, that's amazing! We have won a badge!"

Kate added: "It's hugely special. Mental health has been a learning process for us too ... We want to get everyone talking about it so it hasn't got that stigma it's had."

Watch the moment below:

If you recall, the world took notice of Meghan and Harry's PDA shortly after their engagement reveal. Meghan comforted a nervous-looking Harry by frequently rubbing the small of his back during their photo call and BBC interview. During their World AIDS Day outing, Meghan and Harry couldn't stop holding hands.

And as any royal fan would know, William and Kate never hold hands in public nor display any other kind of affection. Queen Elizabeth II actually set a precedent that encourages royals to keep their hands to themselves.

Albeit a small gesture, Kate's sweet PDA with William is a sign that the royals are loosening up a bit! Check out the video above for more on the royal family.
