Baroness Thatcher's death caused paroxysms of confusion on Twitter where some users were apparently left with the impression that the singer Cher had died.
Members began posting comments on the microblogging site with the hashtag #nowthatchersdead soon after the news was announced.
But it was apparently misinterpreted and led to a flurry of Tweets suggesting it had upset the pop star's fans.
Comedian Ricky Gervais attempted to set the record straight, writing: "Some people are in a frenzy over the hashtag #nowthatchersdead.
"It's 'Now Thatcher's dead'.
"Not, 'Now that Cher's dead'".
Other Twitter users sought to reassure followers. One wrote: "It's OK people, @cher is still very much alive".
