Dave Grohl is not backing down from his criticism of 'Glee.' The Foo Fighters frontman, who in March said, "It’s every band’s right, you shouldn’t have to do f—ing ‘Glee,'" reiterated those comments during an appearance on 'Chelsea Lately' on Wednesday night.

Grohl told the host, "I read somewhere that the creator of 'Glee,' who I never met, and I've really only watched three minutes of the show ... I read something where he was kind of mouthing off about some friends of mine in rock bands. And I just felt like, you know, as a musician, you should be able to say no, should be able to say, 'I don't want to do your show.'"

He continued, "Why is that necessary for you to have to do, as a rock musician? Why should you have to say, 'Ok, Glee, take my song and turn it into a f---ing musical.'"

Ouch. It looks like the 2011 MTV Video Music Award winners for Best Rock Video won't be appearing on 'Glee' anytime soon, unless perhaps Gwyneth Paltrow, broker of peace, can step in and resolve the beef, as she did when Kings of Leon publicly rejected 'Glee' as well.
