It takes two to tango.

Meghan Markle and husband Prince Harry dropped it low as she prepared to give birth to their daughter, Princess Lilibet, in a newly released video from 2021.

For Lilibet’s 4th birthday, the Duchess of Sussex shared a throwback video on Instagram of her and the Duke of Sussex dancing to the viral “Baby Momma Dance Song” while they were in the hospital for their second child’s birth.

In the video released Wednesday, Markle sported a black wrap dress as she twirled around the delivery room, moved her hips and clapped to the music.

Harry, 40, could also be seen dancing across the screen.

The “Suits” alum, 43, and her beau, who sported jeans and a green hoodie, then dropped it low as the song sang, “Drop it down, drop it down down low.”

The couple, who tied the knot in 2018, continued to shake it until the video ended. Dancing is a fun and effective way to shorten labor and promote a natural birth, according to the National Institutes of Health.

“Four years ago today, this also happened,” she captioned the post.

“Both of our children were a week past their due dates… so when spicy food, all that walking, and acupuncture didn’t work – there was only one thing left to do! 😂.”

Markle gave birth to Lilibet on June 4, 2021. She and Harry are also parents to son Prince Archie, whom they welcomed in May 2019.

On Wednesday, the mom of two shared several throwbacks in honor of her little one’s special day, including a photo of her holding Lilibet right after she was born.

“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,” she captioned the post.

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

Markle also shared then-and-now photos of Harry with his daughter, saying they have the “sweetest bond to watch unfold 💕.”

“Daddy’s little girl and favorite adventurer Happy birthday Lili!” she wrote.

Lilibet’s first name was chosen to pay homage to her late great-grandmother Queen Elizabeth II, who had that moniker as a childhood nickname.

The toddler’s middle name, Diana, honors Harry’s late mother, Princess Diana, who died in a car crash in 1997.

Last month, the Sussexes celebrated Archie’s 6th birthday.
