When Radiohead refused to meet Miley Cyrus and Kanye West at the Grammy Awards last month, the starlet threatened to "ruin" them and the rapper refused to stand for their performance. Now the In Rainbows band is fighting back.

Cyrus kicked off the feudin' during an appearance on the Johnjay and Rich radio show and rambled on for more than six minutes about how the band dissed her after she begged her manager to set up an introduction.

"I'm like, these are the people I really want to meet," she said. "I'd freak out. They're my rock gods. These are the only people that I would cry over…My manager asked and said, 'Miley's really obsessed. And they were like, 'We don't really do that.' "

She continued on in disbelief about the Thom Yorke band's lack of interest in meeting the Hannah Montana, admitting she was so disappointed about the diss, she left the show early.

"I left 'cause I was so upset," she said. "I wasn't going to watch. Stinkin' Radiohead! I'm gonna ruin them, I'm going to tell everyone."

The three-time Grammy winners responded by putting the teen in her place…

"When Miley grows up, she'll learn not to have such a sense of entitlement," the quintet said in a statement.

But the Radiohead beef buck doesn't stop there.

During the taping for his episode of VH1's Storytellers, West complained that Yorke snubbed him as well.

"When he performed at the Grammys, I sat the f--k down," the rapper said.

The British "Creep" singer, already in full retaliation mode, concluded a blog post on the band's website with a wink and a nudge to both stars. "Wish us all a safe journey if you still like us and you're not one of those people I have managed to offend by doing nothing," Yorke writes.
