Duchess of Sussex Meghan Markle has shared a rare picture showing Prince Harry holding daughter Princess Lilibet while the four-year-old clutches a bunch of red balloons. Meghan captioned the adorable Valentine's Day post: “These two + Archie = my forever Valentines.”

Harry and Meghan rarely post shots of Lilibet or her brother Archie where their faces can be seen, making this one of the clearest pictures of Lilibet they have ever shared. Both children are being raised in the town of Montecito, California and the picture also shows the sun setting behind a pair of palm trees.

Meghan also shared new pictures of Lilibet in October to mark the International Day of the Girl. Lilibet was seen running across the lawn at the family's California home as Temptations' song 'My Girl' played.

Another shot showed her and Meghan holding hands as they looked over a pond with their backs to the camera. She captioned the snap: "To all the girls - this world is yours. Do everything you can to protect your rights, use your voice, support each other. We will do the same for you. It's your right and our responsibility. Go get 'em girl!"

Meghan and Harry’s daughter Lilibet - named after the childhood nickname of the late Queen Elizabeth II - is seventh in line to the throne. Her full name is Lilibet Diana Mountbatten-Windsor.
