'Glee' Creator Says 'F--- You' to Kings of Leon for Snubbing Show

What do you do when two bands, a minor blip among countless world-class performers clamoring to have their music featured 'Glee,' decide to snub the show?

If you're show creator Ryan Murphy, you get mad. Publicly.

In a Hollywood Reporter cover story on the show, Murphy offered blunt rebuttals to rock groups Kings of Leon and Guns N' Roses, both of whom have declined the show's offers to include their music in episodes.

"F--- you, Kings of Leon," he said. "They're self-centered a------s ... It's like, OK, hate on arts education. You can make fun of 'Glee' all you want, but at its heart, what we really do is turn kids on to music."

Turning to Guns N' Roses -- whose guitarist Slash said that "'Glee' is worse than 'Grease' and 'Grease' was bad enough" -- Murphy said, "Usually I find that people who make those comments, their careers are over; they're uneducated and quite stupid."

Kings of Leon have defended themselves by saying several times that their decision was nothing personal, and that in the past they've turned down several requests from corporations, film producers and others. Still, drummer Nathan Followill couldn't help but take Murphy's recent bait. He headed to Twitter Wednesday morning to fire a few hot-headed volleys in return.

"Dear Ryan Murphy," he wrote. "Let it go. See a therapist, get a manicure, buy a new bra. Zip your lip and focus on educating 7yr olds how to say f---."

In a follow-up message, Followill apologized to anyone who found his words homophobic or misogynistic, but kept his original post up.

Coldplay, Gorillaz and Bryan Adams have also publicly declined the show's offer, although Coldplay recanted last summer and made their entire catalog available.
