Creator of 'Glee', Ryan Murphy, has hit back at artists that decline offers to star in the hit television show because his only intention is to "turn kids on to music".

Guns N' Roses recently turned down the chance to have their iconic songs featured on the show and now Kings Of Leon have followed suit, which caused Murphy to speak out about the situation. He told The Hollywood Reporter:

"Fuck you, Kings of Leon,”

"They’re self-centered assholes, and they missed the big picture. They missed that a 7-year-old kid can see someone close to their age singing a Kings of Leon song, which will maybe make them want to join a glee club or pick up a musical instrument. 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.”

The 'Sex On Fire' rockers' front man, Caleb Followill, also released a statement supporting the band's decision to avoid 'Glee', and said:

"This whole Gleething is a shock to us. It’s gotten out of hand. At the time of the request, we hadn’t even seen the show. It came at the end of that record cycle, and we were over promoting [“Use Somebody”]. This was never meant as a slap in the face to Glee or to music education or to fans of the show. We’re not sure where the anger is coming from. We just said no to a license for a TV show, which we do a lot.”
