As the world waited for the birth of the royal baby; they tweeted.

According to Twitter's U.K. blog, at its peak, the birth sparked over 25,000 tweets per minute and spurred the use of hashtags like #RoyalBabyBoy #RoyalBabyWatch and simply #RoyalBaby, which was used more than 900,000 times.

In a history-making move, Kate Middleton and Prince William's official Twitter account kept social media audiences updated throughout the day.

"Her Royal Highness The Duchess of Cambridge has been admitted to St. Mary's Hospital, Paddington, London in the early stages of labor," Clarence House tweeted early Monday morning as Middleton was admitted to the Lindo Wing.

Following the announcement, the news was mentioned over two million times on Twitter, with the highest number of tweets coming from the U.K., the United States, Canada, France and Italy.

The birth announcement, traditionally done by placing a document including the baby's gender, weight and time of delivery on an easel outside of Buckingham Palace, was also made via Twitter.

"Her Royal Highness The Duchess of Cambridge was safely delivered of a son at 4:24 p.m. The baby weighs 8lbs 6oz. The Duke of Cambridge was present for the birth," the royal account shared in three separate tweets. The first was re-tweeted over 15,000 times.

Tons of celebrities also got in on the royal social media frenzy.

"#BABYWATCH UPDATE! Kate Middleton has gone into labor. A royal baby is being born! I repeat! A #ROYALBABY is being born," "Modern Family" star Sarah Hyland tweeted early Monday morning.

"'I don't even care.' Me, on the royal baby, as I furiously scroll Twitter for updates," shared supermodel Chrissy Teigen.

"It's all so exciting," added Kelly Osbourne.

Even with the birth over and word that the baby and his royal parents are doing well, Twitter users are still glued to their feeds hoping for another bit of news—the little one's name! It has yet to be announced.
