Miley Cyrus' representatives have been forced to confirm she is still alive after an Internet hacker broke into the teen superstar's 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, which told fans: "Miley died this morning after being hit by a drunk driver. She always told us if anything ever happened to her then tell her loyal fans first before the public. R.I.P Miley, we'll never forget you!"

The video, set to the Hannah Montana star's sad new song Goodbye, upset the singer/actress' friends and family, who had to quickly deny the claims - insisting it was the work of a twisted hacker.

According to celebrity blogsite Perezrevenge.com, Cyrus' boss - the head of Hollywood Records - leaves a statement assuring worried fans the teen sensation is perfectly fine.

The comment reads, "This Is The President Of Walt Disney Records And I Can Honestly Say That Miley Cyrus Aka Hannah Montana Is Not Dead And She Is Currently In New York City Doing The Final Episode Of Trl. We Are Doing Our Best To Find Out Who This Hacker Is. Thanks You For Your Concerns Miley Fans."
