Simonetta Stefanelli isn't dead.
The Italian actress, best known for her role in The Godfather as Apollonia Vitelli-Corleone (aka Michael's Sicilian Wife Who Gets Blown Up), has apparently had a lot of problems over the past few years with a rumor circulating the Internet that she had died in 2006. The issue became so persistent (and widespread), that her death was reported in Newsweek.
Ms. Stefanelli, Things I've Learned from Wikipedia is on your side.
