Bill Cosby is not dead but did become a trending topic as yet another celebrity death hoax was sparked via Twitter and Facebook on Monday. Fans raced to the social media sites to affirm whether or not the Bill Cosby dead trend was true or false. This, however, was not the first time, but at least the fifth time, Cosby fell victim to "upsetting" dead hoax rumors.

In 2010, Twitter and Facebook also declared news of Cosby's death. The comedian called into to "Larry King Live" to talk about his alleged passing that was only true on Twitter.

"I don't want to do this anymore, because this is my fourth time being reported [dead]," he said.

"Emotional friends have called about this misinformation," Cosby posted on his own Twitter account. "To the people behind the foolishness, I'm not sure you see how upsetting this is."

"BREAKING: Bill Cosby has died....only on twitter...not in real life. Quit starting stupid twitter death hoaxes," @BreakiingNews posted on Twitter yesterday.

"Y'all really need to stop trying to kill off Bill Cosby on these social networks," @runrgrl26_2 added later.

The Twitter continues to swirl with responses to the false report.

Just yesterday, Bill Nye The Science Guy was trending on Twitter for his so-called death as well. Other victims to the celebrity death hoaxes on Twitter include Cher, Jon Bon Jovi, Lindsay Lohan and Justin Bieber--who has actually been targeted more than once. The 18 year-old "Boyfriend" singer was supposedly the victim of a shoot out at a night club in New York and also dead because of overdosing on drugs.

Bill Cosby is most known for his break-through TV sitcom, "The Cosby Show," in the 1980s. The NBC sitcom went on to be the higest ranking sitcom of all-time. The show was unique in it's family-oriented humor and situational comedy involving an educated, successful, African American family.
