Prince Harry and Duchess Meghan are no strangers to PDAs, with the pair often being seen holding hands and grazing arms during their public appearances.
And things have only ramped up during their current tour of Australia and the South Pacific after the couple announced they were expecting their first child together little over a week ago - some might even say the tour has turned into a full-blown babymoon for the royals.
But there was one super sweet moment the couple shared that you might have missed, and it just goes to show what a perfect match the couple is for each other.
While boarding a flight from Queensland to Fiji on Monday, pictures of the couple show their smart-casual in-flight outfits.
And while their shirt and pant ensembles are something many people wear on flights, there's something a little special about Harry and Meghan's when you look a little closer.
The pair sported button-down shirts from the same label - Frank & Eileen.
The shirts themselves even have their own gender-specific names: Meghan's white Italian linen shirt was called the 'Eileen' while Harry's black Italian cotton shirt was named 'Luke'.
What's more, the brand has a romantic love story as sweet as Meghan and Harry's behind it. According to People, the company was named after founder Audrey McLoghlin's grandparents who were married in Ireland in 1947.
On purpose or not, there's no denying this was an adorable twinning moment between Harry and Meghan.
During their royal tour Down Under, the newlyweds have shared some sweet moments with each other, and with royal fans.
On Wednesday, Meghan delivered a rousing speech during an anniversary event at the University of the South Pacific in Fiji. Proud Prince Harry was clearly in awe of his wife when he stepped up to the podium stating: "No way that I could follow my wife after that."
While in Sydney, the couple also shared a beautiful moment with war widow Daphne Dunn. The 98-year-old is no stranger to Harry, having met him on a number of occasions and sharing many fond embraces with the red-headed royal.
During a public walkabout outside the Opera House, Daphne and Harry met again, and she asked him to introduce her to his new wife.
When she came over to the pair, the excited Duchess exclaimed: "Oh my goodness, is this Daphne?"
"She's said she had heard all about me, she's so beautiful," Daphne said afterwards.

During his Invictus Games opening speech in Sydney on Saturday night, Prince Harry also referenced his baby joy.
"I have been so proud to be able to introduce my wife to you and we have been so happy to be able to celebrate the personal joy of our newest addition with you all," he told the ecstatic crowd.
While in Sydney, Harry also came across a young nine-year-old fan named Sethunya Gibbons who was wearing a feminist-slogan T-shirt reading: "Girls can do anything!"
Knowing Meghan is a passionate woman's advocate. Harry was quick to summon his wife over to introduce the pair.
To everyone's surprise, the young girl had striking similarities to Meghan in the looks department as well, so the ever-charming Harry asked if the pair wanted a photo together.
Sethunya was clearly delighted by the royal couple's act of kindness, and while the picture technically broke royal walkabout protocol, it was absolutely worth it.
