Meghan Markle's heartfelt tribute to husband Prince Harry on Valentine's Day did not go unnoticed and royal fans had one thing to point out.

The Duchess of Sussex posted a new black and white photo with her husband on Friday to mark the special day and accompanied it with a sweet message.

In the photo, the couple are seen casually dressed and sharing a kiss midway through a meal.

Meghan wrote: "Back home taking care of our babies, and missing my Valentine, as he continues on at the Invictus Games, changing lives and reminding all of us of the power of healing and resilience through these incredible veterans and their families.

"Beyond proud of my husband and what he's created.

"My love, I will eat burgers & fries and fish & chips with you forever. Thank you for you. #lovewins"

Royal fans were quick to comment on the photo on social media, with many of them spotting a key detail in Meghan Markle's message - her promise to always "eat burgers and fries and fish and chips with you forever".

One user wrote on X: "'My love, I will eat burgers & fries and fish & chips with you forever. Thank you for you.' A simple message from Meghan to Prince Harry that beautifully captures their enduring love. I love their love."

Another one said: "That was freakin beautiful."

A third one commented: "Meghan really said 'My love, I will eat burgers and fries and fish and chips with you forever'. She loves that man your honour. Their love is everything."

The Duchess's post comes just a few days after leaving the Invictus Games for in Canada that Harry is hosting to go back to California and look after their two children, Prince Archie and Princess Lilibet.

Later that day, Meghan also gave a rare glimpse of her children helping her prepare heart-shaped treats on her Instagram stories.

The video showed cutting heart-shaped strawberries and preparing Valentine's themed food alongside her children, with the song L-O-V-E by Nat King Cole, on her Instagram story.

The mother-of-two showed off her culinary skills, decorating pink snacks with her daughter Lilibet before carrying the plate outside, following her son Archie.

Neither child's face could be seen in the video, in keeping with the couple's attempts to maintain their privacy.
