Jack Black became the latest celebrity victim of a death hoax after the Twitter account of Tenacious D, an American comedy rock duo that features Black and Kyle Gass, got hacked.

"I'm sad to officially announce the death of Jack Black at the age of 46, rest in peace brother," the message read. "It is with a heavy heart I am to announce that Jack Black passed away last night at 3.37 am. The cause of death is yet unknown."

Believing the message to be true, a number of fans soon started posting their condolence messages. But the perpetrator soon put everyone out of their misery by stating that it was just a prank. "Calm down guys! It's just a prank bro, look there's the camera. The Legend is still alive, it is ok guys :)." The unidentified person also urged everyone to follow him @Ruthless, but the account has since been suspended.

The hoax message was up on the account for about three hours before it was removed. "WE had our Twitter account hacked. We can assure you that Jack is ALIVE and WELL and that this was a sick 'prank'," a tweet from the account read.

Interestingly, Tenacious D's Twitter account was just one celebrity account that was hacked on Sunday. Hackers hit Tame Impala, Keith Richards and Bon Iver the same day.

Tame Impala's account featured a bomb threat posted to Jet Blue airlines' feed that read, "I HAVE 15 C4'S IN MY BAG AND 12 PIPEBOMBS IN MY BAG ALSO."

Bon Iver's Twitter handle was changed to "@ihavelegcancer" and the hacker posted a derogatory comment about the death of boxing legend Muhammad Ali, who passed away on Friday.

A series of hateful tweets were sent out from Richards' handle, claiming that he loved killing people.
