One must keep up with the times, and the Duke and Duchess of Cambridge are doing just that as it is revealed that they will announce the birth of their second child via Twitter.

Traditionally royal births are announced via the Buckingham Palace easel, but Prince William and his wife Kate Middleton will be telling the world about their new bundle of joy way before the doctor has a chance to post the official birth notice on the historic easel in London. Using the @KensingtonRoyal handle, the couple will reveal the birth using the hashtag #royalbaby and also detail whether Prince George has a little brother or a sister.

The Duchess is currently believed to be up to four days overdue, and many believe that the blue-blooded baby will arrive on 29 April, which also marks William and Kate's fourth wedding anniversary.

Which sex do you think the baby will be?
