Glee creator Ryan Murphy is on the warpath again - he's taken aim at Slash for snubbing the chance to have his Guns N' Roses songs included in the hit show, branding the rocker "stupid".
The writer is currently feuding with the Kings Of Leon after calling them "self-centered a**holes" for refusing to let their hit Use Somebody be featured on the program.
Slash revealed earlier this month that he had rejected a suggestion for a Guns N' Roses-themed Glee episode, saying, "We got asked about that (Glee) once already but it got turned down... Glee is worse than Grease and Grease is bad enough..."
And Murphy has now taken aim at Slash for his criticisms of the show, blasting the guitarist in a scathing rant to RollingStone.com.
He says, "Usually I find that people who make those comments, their careers are over; they're uneducated and quite stupid."
