The Twitter hash tag that was created after Margaret Thatcher's death caused widespread confusion among the users of the social network.
Tweeters then mistakenly spread the news of Cher's death Monday and began paying tribute to the singer, who is still very much alive, the Evening Standard reported.
Comedian Ricky Gervais was one of the tweeters who attempted to stop the confusion.
"Some people are in a frenzy over the hash tag #nowthatchersdead. It's "Now Thatcher's dead". Not, "Now that Cher's dead," he tweeted.
