Nope. It's just another celebrity death hoax.

No, Mel Gibson isn't dead. The story is merely the latest in a long line of recent internet death rumors spread on sites like Twitter, Facebook, and YouTube.

This most recent rumor seems to have started when an individual with 15,000 Twitter followers tweeted "Mel Gibson RIP." The poster later explained he was referring only to Mel Gibson's career, which many feel is in jeopardy after high-powered talent agency WME dropped him as a client in the wake of widely-reported, expletive-laced comments he made to his ex-wife Oksana Grigorieva. The former couple are locked in a bitter custody battle.

While internet death hoaxes are nothing new, the advent of social media and user-generated content has certainly increased their frequency and the speed with which they spread. This year alone Russell Crowe, Justin Bieber, Jackie Chan, Lindsay Lohan, and Taylor Lautner have all been the subject of similar rumors.

Of course, false death stories didn't originate with the web. Queen Elizabeth II, Joe DiMaggio, Gerald Ford, Marcus Garvey, Harold Pinter, and Ernest Hemingway all had their deaths reported – in some cases by major media outlets – while they were very much alive.

Mark Twain responded to premature news of his own demise with a humorous account in the New York Times that included the oft-misquoted quip, "The report of my death is an exaggeration."

Today he probably would have just tweeted it.
