Brexit shook the world, and a number of people had a number of things to say. The issue generated over 2m tweets. Social media users reacted with a mix of "surprise, gloating, and wry humour."

The Brexit news was a historic milestone, as is well known, of course. There were 33 million who put in their vote for it. UK media outlets said that 52 to 48 percent were in favour of the exit, which was declared early Friday morning. The British pound dropped to its lowest level since 1985. And Prime Minister David Cameron resigned his post.

A storm broke out in the social media, with celebrities letting loose a volley of words.

"I can't get my head around what's happening in Britain," Late Late Show host James Corden tweeted. "I'm so sorry to the youth of Britain. I fear you've been let down today."

The author with the magic touch, J.K. Rowling, said: "I don't think I've ever wanted magic more." She later added: "Goodbye, UK."

Lindsay Lohan, currently a Londoner, was alive on twitter when the message was beamed. However, she quickly deleted her messages. "Good luck with the pound," one tweet read. "Will take you about 15 years to get it back up #REMAIN instead."

She went on to tweet about a number of issues, including the value of British currency as well as the impact of the EU on UK's workplace.

Her concluding remarks were: "One thing for sure the #referendum results are very close, but also showing a difference of opinion across #Britain."

A number of people were quite disbelieving, as they could not imagine that she was writing a lot of political messages. But she was clear about her stand: "I have not been hacked."

Here are a number of other celebrity messages:

Ellie Goulding: "Heartbroken to hear the news. ...I truly believe this is one of the most devastating things to happen during my lifetime. I felt a fear I've never felt this morning."

Jaime King: "That was f**king intense UK. We are with you during this time."

Hugh Laurie: "Congratulations exits. The reverse is across and down, easy on the clutch."

Michael Sheen: "Wales votes to trust a new and more right wing Tory leadership to invest as much money into its poorer areas as EU has been doing #EUref"

Lupe Fiasco: "Britain Leaves The EU, Colombia Ends Civil War and I got my VR headset...what a day!!!"

Ryan Seacrest: "Shocking news out of UK this morning. Definitely a day for the history books... #Brexit"
