MILEY CYRUS is not dead.

Early Sunday, a video posted on the "Miley and Mandy Show" YouTube page falsely claimed she'd been killed by a drunken driver.

Set to the sound of Cyrus's weepy new single "Goodbye," the more than two-minute-long video featured a grim message from Miley's BFF Mandy Jiroux.

Jiroux's supposed message reads: "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."

But Jiroux tells E! News that the video is the work of "a hacker" -- not her -- and that, as of Sunday afternoon, the hacker video was in the process of being removed from the site.

Mandy also posted this on her official Myspace page: "some1 hacked the miley and mandy youtube account and we cant [sic] get back into it just yet!! Miley is OK!!"
