George R. R. Martin has confirmed on his blog that he is indeed "not dead yet" after people mistook him for George Martin, the 90-year-old Beatles' producer who passed away over the weekend.
"I have to go with Mark Twain and insist that the rumors of my death have been greatly exaggerated," he wrote, noting that he is "still here, still writing, still editing, still going to movies and reading books," and that he expects "to hang around for quite a while yet."

The Rock was less than impressed when he heard the news that he'd died while filming a dangerous stunt for The Fast And The Furious 7 in New Zealand in April 2014. The rumour was in particularly poor taste as his friend and co-star Paul Walker had died in a car accident less than six months previously.
Understandably, The Rock took umbrage, tweeting that he'd like to kick the person responsible for the rumours with his "dead foot".
