The picture didn't feature their son Prince Archie, six, but Meghan did mention him in her heartfelt caption. The caption read: "These two + Archie = my forever Valentines [red-heart emoji]." Harry, 41, and Meghan, 44, are known to be incredibly protective of their children, with them rarely seen by the public. Even when Meghan shares pictures of Lilibet and Archie on social media, she clearly makes sure to hide their faces - but Lilibet's side profile is clearly shown in the latest snap.

Taking to social media, fans appeared delighted by Meghan's latest snap - with many focused on Lilibet's outfit.

One commented: "Princess Lilibet being a little ballerina is so adorable, I can't [teary-eyed emoji] [heart-eyed emoji]."

Another added: "Awww Princess Lilibet Diana in her signature pink, protected in the arms of her best Valentine."

A third adding: "Awww my poor heart! Prince Harry holding his little ballerina, Princess Lilibet in all pink [and] holding a bouquet of red balloons! Happy Valentine's Day to the father [and] daughter duo and the entire Sussex family!"

Meghan shared a rare glimpse of Princess Lillibet on Instagram last March, with the little one dressed in an all-pink ensemble as she played cards with international tennis star Serena Williams.

While Meghan is known for her chic formal attire, she opted for something cute and comfortable for Lilibet.

Lilibet also wore all-pink in a snap posted by Meghan in October in honour of International Day of the Girl.
