Kate Middleton and Prince William's sweet Father's Day post features previously unseen photos of their children

Kate Middleton and Prince William's affectionate Father's Day video on Instagram is making royal fans swoon.

• To honor all of the special dads in their lives, Kate Middleton and Prince William shared several photos in a touching Instagram video clip.
• Four generations of the royal family appear in the post as well as a previously unseen snap of Kate and William's three children.
• In other royal news, an unpublished interview with Princess Margaret reveals her beautiful words about her sister, the Queen.

In a new Instagram clip for Father's Day, the Duke and Duchess of Cambridge shared several new photos—Kate and her father Michael Middleton on her wedding day, a young Prince William and Prince Harry alongside Prince Charles, a previously unseen photo of Prince William and his three children, and Prince Philip and the Queen alongside several of their 11 great-grandchildren. 

"Wishing fathers everywhere a happy Father's Day," the caption read. 

With over one million views and counting, fans are certainly anxious to take a look at the snapshots—the image of William alongside George, Charlotte and Louis being a favorite amongst the commenters. 

"the trooping photo is so adorable" commented one royal fan, while another said, "That new picture on the bottom left is so beautiful!!!"

Although Prince Harry made an appearance in the photo collage as a young child, he and his children, Archie and Lilibet Diana, were not included in the roundup. Photos of Lilibet on WhatsApp have made the rounds on the royal family's group chat, but the public is still waiting for a peek of Prince Harry and Meghan Markle's newborn daughter.

While the Duke and Duchess of Cambridge shared the sweet Father's Day montage, the Duchess of Sussex chatted in an interview with NPR. Meghan Markle discussed a special Father's Day for Prince Harry, her new picture book, The Bench, and what she hopes readers take away from the personal story.

"Any child or any family hopefully can open this book and see themselves in it, whether that means glasses or freckled or a different body shape or a different ethnicity or religion," Meghan said on NPR's Weekend Edition.
