Miley Cyrus railed on her now ex-fave band RADIOHEAD when they declined her offer to meet her backstage in LA a month ago.

RADIOHEAD's "people" were quoted as saying,"the band doesn't really do that."

Furious over her rejection she told a Portland radio station that, " The reason I am in this business is to make people happy.  I left 'cuz I was so upset.  I wasn't going to watch.  Stinkin' Radiohead! I'm gonna ruin them; I'm going to tell everyone!"
