Miley Cyrus alive and well

Miley Cyrus' best friend has been forced to deny claims the 'Hannah Montana' star is dead.

Mandy Jiroux - who creates videos with Miley as part of the 'Miley and Mandy Show' on video sharing website YouTube - insists the 15-year-old star is fit ad healthy, despite footage claiming she had been hit by a drunk driver appearing on the internet.

The video, posted on the 'Miley and Mandy Show' YouTube page, was alleged to be from Mandy and said: "Hey guys, this is Mandy and I have some very sad news. We're very hurt to tell everyone this, but Miley died this morning after being hit by a drunk driver.

Miley told us if anything ever happened to her then we should let her fans know before the public. R.I.P. honey, we will miss you so much."

A furious Mandy has now posted a written response on her personal MySpace page declaring Miley alive and well.

She writes: "Someone hacked the 'Miley and Mandy Show' YouTube account and we can't get back into it just yet! Miley is OK!"
