The Duchess of Sussex has released a video of herself twerking while pregnant with Princess Lilibet to celebrate her daughter’s fourth birthday.

The Duchess, 43, can be seen performing the dance move, which involves hip-thrusting while in a squat position, with her husband in hospital while waiting to give birth to their daughter, who is seventh in line to the British throne.

In the Instagram caption, Meghan said that she was using the dance technique to induce birth, which she revealed was a week late, for both Princess Lilibet and Prince Archie, six.

She explained: “Four years ago today, this also happened. 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!”

In the video, Meghan can be seen cradling her stomach before looking over at the Duke of Sussex and starting to dance to Baby Mama Dance by Mic Drop Mama.

TikTok trend

The song, which includes the lyrics “drop it down, drop it down down low”, was the focus of a TikTok trend where pregnant women showcased their dance moves at 39 weeks (nine months).

It is not confirmed that dance moves such as twerking induce labour, but some induction tips will include being as mobile as possible.

On NHS Lothian’s website advising women what they can do while having an induction, it states: “Walking, dancing, swaying, squatting and using a birth ball all help to keep you mobile and active, which can help your labour to establish.”

While the Duchess did not make clear her reason for sharing the video, it marked the third post she made on Instagram in celebration of Princess Lilibet’s fourth birthday.

The other posts included new family photos of her daughter, who has rarely been pictured facing the camera in recent years.

The posts included a black and white picture of herself holding her daughter on what appears to be a boat as well as shots of the Duke walking hand-in-hand with his daughter.
