No, Cher fans, the singer and actress did not die. The Twitter hashtag "#nowthatchersdead" is meant to be read as "now Thatcher's dead" — not "now that Cher's dead."

Margaret Thatcher, the United Kingdom's former prime minister, died Monday at age 87 following a stroke. Website Is Thatcher Dead Yet? quickly reacted, encouraging people to reveal how they're celebrating the death via tweets with hashtag #nowthatchersdead.
