Prince William and Kate Middleton’s baby No 2’s birth announcement will be made via Twitter, People magazine reported.

Once the second royal baby is born at St. Mary’s hospital in London, the news will be announced via an official email and Kensington Palace will update its social media accounts, including Twitter and Instagram.

The royal baby tweets and Instagram posts will announce the baby’s gender, time of birth, and weight.

In January 2015, Kate Middleton, Prince William, and Prince Harry officially joined Twitter and Instagram under the handle @KensingtonRoyal.

As with Prince George’s birth in 2013, a birth notice will be placed on an easel outside of Buckingham Palace that will include the baby’s gender, weight and time of birth.

For the first time, a royal announcement will be a mix of tradition and technology.

Prince William and Kate Middleton will make the traditional appearance on the steps of the hospital when they leave.

Weeks ago, parking restrictions were put in place outside of that legendary brown door where Prince Will and Kate Middleton will present their baby to the world, much like they did when Prince George was born.

A sign outside of the hospital says the restrictions are in place for a “special event”.

Kate Middleton’s pregnancy with the second royal baby is overdue, but according to a new report, a birth should be expected within days.
