The hotly-anticipated news has finally been confirmed: Kate, the Duchess of Cambridge is pregnant.
Twitter has exploded with excitement over the arrival of a #royalbaby, the euphoria only slightly dampened by the news that Kate has been taken to hospital with acute morning sickness.
Officials rushed to be the first off the mark to congratulate everyone's favourite royal couple, with David Cameron beating Ed Miliband in the royal baby Twitter race.
Although both tweets were particularly anaemic in content, Miliband scored extra points for almost managing to squeeze one nation into his royal baby tweet.
Twitter's frenzied congratulations were peppered with speculation over the sex of the baby and the name of the baby, with some suggestions more likely than others.
Some even suggested what the baby would weigh, the lifestyle of the baby or even what the baby might look like.
Paddy Power has offered 6/1 that the baby will be ginger, odds accompanied by a startled realisation that the royal baby would have Prince Harry for an uncle.
The joyous announcement was also accompanied by a collective groan by some royal humbugs as the interests of anybody who wasn't either a) royal or b) expecting were drowned out by a tidal wave of maternity madness.
With interest soaring in anything royal baby related, all media outlets attempted to squeeze in their own angle on the exciting news.
Monday's baby bulletin brought out the caustic best in some Tweeters.
But for many the royal baby was merely an excuse for a jolly good Twitter knees up with royal joviality abounding.
