Meghan Markle celebrated her daughter Princess Lilibet’s 4th birthday by sharing a never-before-seen video of herself dancing while pregnant. The Duchess of Sussex posted the throwback clip on Instagram, showing her and Prince Harry recreating a viral TikTok challenge inside a hospital room.

The video, set to the song “Baby Mama” by Cameron Henderson, features the couple playfully dancing in an effort to induce labor. Meghan captioned the post: “Four years ago today, this also happened. Both of our children were a week past their due dates… when spicy food, walking, and acupuncture didn’t work – there was only one thing left to do!”

The duchess followed the video with a series of intimate family photos. Meghan wrote: “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.”
