Sinead O'Connor has never been one to bite her tongue: Now the singer-songwriter is shaming Rolling Stone for putting reality-TV queen Kim Kardashian on its cover.

"What is this c*nt doing on the cover of Rolling Stone?," O'Connor posted on Facebook, with a screenshot of the mag's new issue.

"Music has officially died. Who knew it would be Rolling Stone that murdered it? Simon Cowell and Louis Walsh can no longer be expected to take all the blame. Bob Dylan must be fucking horrified. #boycottrollingstone"

Mr. Dylan had no immediate comment.

Promoting the issue on its own Facebook wall, Rolling Stone declared, "Reality-TV juggernaut, selfie queen, actress, model, mother, Internet-breaker, entrepreneur and video game subject Kim Kardashian has something to say: "I believe that I am so much smarter than I'm portrayed."

In the interview, Kardashian discusses learning about her step-father's gender struggle when she was 22, and how O.J. Simpson stayed with her family during his infamous murder trial.
