Sharon Stone has received death threats in the past. The 54-year-old actress - who has been a spokeswoman for the American Foundation for AIDS Research since 1995 - was astonished by the messages she received in response to her charity work, and admitted she had to be more ‘’careful’’ in her life, though she refused to be deterred in her quest to help others. She said: ‘’When I started doing charity work, people thought I was only doing it for press - they called me the new Zsa Zsa Gabor. The adversity was awful. My life was threatened - someone wanted to kill me.                                                        –Agencies
