Reporters are staking out a hospital, news websites have launched live-blogs and a "forensic artist" has even engineered images of a yet to be born child.
It's official: Prince William and wife Catherine, the Duchess of Cambridge, are expecting a baby.
Clarence House broke the news on Twitter - the tweet, simply reading "The Duke and Duchess of Cambridge are expecting a baby", has been re-tweeted more than 2,500 times.
The Duke and Duchesses website has since gone down due the heavy traffic.
Following the announcement, the hashtag "#Royalbaby" was trending worldwide on Twitter, while in the UK "#Kate" and "#UnlikelyRoyalBabyNames" were also trending.
