Sinead O’Connor wants Miley Cyrus to stop prostituting herself to the music industry.

The outspoken Irish singer-songwriter penned an open letter to the twerk-happy pop star, condemning her recent slew of vulgar performances and music videos. The harsh words come on the heels of Cyrus’ Rolling Stone interview in which she named O’Connor as a musical influence. In fact, Cyrus told the mag she modeled her “Wrecking Ball” music video after O’Connor’s video for her 1990 single “Nothing Compares 2 U.”

“I am extremely concerned for you that those around you have led you to believe, or encouraged you in your own belief, that it is in any way ‘cool’ to be naked and licking sledgehammers in your videos,” O’Connor wrote on her site. “It is in fact the case that you will obscure your talent by allowing yourself to be pimped, whether its the music business or yourself doing the pimping.”

The music legend also warned the 20-year-old about the perils of the music biz.

“Nothing but harm will come in the long run, from allowing yourself to be exploited, and it is absolutely NOT in ANY way an empowerment of yourself or any other young women, for you to send across the message that you are to be valued (even by you) more for your sexual appeal than your obvious talent,” she wrote, adding that music execs “will prostitute you for all you are worth, and cleverly make you think its what YOU wanted.”

Cyrus responded via social media, referencing Tweets O’Connor wrote last year following her suicide attempt.

If anyone can benefit from these comments, it might be Lorne Michaels and “Saturday Night Live.” Will Cyrus rip a photo of O’Connor when she hosts the NBC show this weekend?
