Meghan Markle posts adorable unseen photo of Harry and Lilibet in birthday tribute

Meghan Markle has shared a rare photo of Prince Harry and Princess Lilibet, to mark her fourth birthday.

The adorable image sees Prince Harry holding his daughter when she was a baby, with the little one looking into his eyes.

"The sweetest bond to watch unfold," Meghan wrote alongside the Instagram post today (4 June).

"Daddy’s little girl and favorite adventurer.

"Happy birthday Lili!"

The sweet photos come just hours after Meghan shared a series of snaps of Lilibet, writing on the social media platform: "Happy birthday to our beautiful girl!

"Four years ago today she came into our lives - and each day is brighter and better because of it.

"Thanks to all of those sending love and celebrating her special day!"

The Duchess of Sussex shared a gorgeous black and white snap where she's cradling her little girl on what looks like a boat.

The glimpse of Lilibet's face is the most the public have ever seen of Harry and Meghan's second-born, as she's largely been kept out of the limelight since her birth in 2021.

Meghan also sweetly included a picture of the day Lilibet was born, in black and white.

Meghan, 43, and Prince Harry, 40, tied the knot in 2018 before welcoming their first child Prince Archie, now six, a year later, before their daughter came along.

In 2020, the couple stepped back from their Royal duties and moved to California - Meghan's home state.

The birthday girl's full name is Lilibet Diana Mountbatten-Windsor, which is a homage to more than one member of the family.

Last month, Meghan shared a tribute to her eldest child, Archie, to mark his sixth birthday.

In the image, Archie can be seen peering over a balcony, facing away from the camera.

The youngster appears to be looking towards the beautiful sunset in the background, with Meghan writing alongside the post: "Our son. Our sun.

"Happy 6th birthday to Archie!

"Thank you for all of the love, prayers, and warm wishes for our sweet boy. He’s six! Where did the time go?

"(And for all of you who came to celebrate with us at his party last weekend, thank you for making his birthday so incredibly special)."

After Meghan posted the image online, people were quick to comment, with many saying the same thing.

Plenty of fans commented on Archie's height, with one writing: "What a beautiful picture of Prince Archie, he is growing so tall. Happy birthday Archie."
