Teen star Miley Cyrus has launched an attack on the internet hacker who broke into her YouTube account and falsely claimed she had died in a car crash.

A video was uploaded onto Cyrus' official page on the video sharing website on Sunday, telling fans she was the victim of a drink driving accident.

The allegations upset her friends and family, who quickly denied the claims - blaming the incident on an internet hacker.

But the 15-year-old insists she's grown accustomed reading fictional stories written about her.

Pretending to be unaware of the event, she jokes with TV reporters on E!, "What happened? Did I die, like, bungee jumping, getting bulldozed, what happened this time? I got hit by a drunk driver! Ok, good. Wait. What? On my Web page? No. My Web page got hacked?"

When details were cleared up, Cyrus admitted she was "ticked" at the culprit behind the computer screen.

She added, "I'm gonna, like, smack 'em!"
