Demi Moore and her score of Twitter followers Friday helped thwart a possible suicide attempt by a distraught California woman.
"Getting a knife, a big one that is sharp. Going to cut my arm down the whole arm so it doesn't waste time," said the message sent to Moore by a user of the social networking site.
"Hope you are joking," wrote back Moore.
"Gbye...gonna kill myself now," the woman responded.
A San Jose police spokesman said the department had received a number of calls from Twitter users about the suicide threat and sent officers to the 48-year-old woman's home.
Moore's husband, Ashton Kutcher, Twitted his congratulations.
"Wifey reported a suicide attempt based on a...tweet she got and saved someones life. The woman is in the hospital now."
About 383,500 people follow Moore's Tweets.
