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 and 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"                                                                                   - EXPO
