MILEY CYRUS PISSED OFF AND THREATENS TO RUIN RADIOHEAD FOR REFUSING TO MEET HER.

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.

I guess money doesn't always talk. LOL! Wonder how Yeezy dealt with his radiodiss?

LIL WAYNE MAKES LYRICAL ATTACK ON SHARPTON!

Rapper LIL WAYNE has lashed out at U.S. civil rights leader REVEREND AL SHARPTON in the lyrics to a new song, branding the minister a "nobody". On the track Misunderstood from his new album Tha Carter III, the Lollipop hitmaker takes aim at the race activist, rapping: "You are nobody to me/You're just another Don King (boxing promoter) with a perm/Just a little more political/And that just means you a little more un-human/Than us humans... F**k Al Sharpton and anyone like him." But Sharpton insists he takes no offence to the slur, reported by AllHipHop.com - because he claims Lil Wayne has no credibility as a musician. Hey Al, white people know him now!

He says, "While some of the rappers don't like the fact that Rev. Sharpton has been leading marches against the degradation of women in music, a Gallup (opinion) poll released last week revealed that Reverend Sharpton has a 50 per cent approval rate among African-Americans. "So why dignify a response to one rap artist who doesn't even say anything substantive?"
