Sinead O'Connor has written a hard-hitting open letter to Miley Cyrus.
The troubled 47-year-old Irish singer felt compelled to put pen to paper after Miley revealed her recent controversial Wrecking Ball video was inspired by Sinead's hit Nothing Compares 2 U.
In her promo, 20-year-old Miley swings on a wrecking ball with no clothes on and writhes around on the floor before licking a sledgehammer.
The first few seconds echo Sinead's video, as the camera is close to Miley's face as she cries. But that's pretty much where the similarities end.
And it looks like Sinead hasn't taken Miley's revelation in Rolling Stone magazine as a compliment.
She writes: "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.
"It is in fact the case that you will obscure your talent by allowing yourself to be pimped, whether it’s the music business or yourself doing the pimping."
She issues a stark warning to the former Hannah Montana Disney star, who's done her best to shed her Disney image with raunchy videos, dances and outfits.
Sinead is more than qualified to give advice, as she has struggled with bipolar disorder throughout her career and has even attempted suicide.
She continues: "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."
Sinead adds: "The music business doesn’t give a s**t about you, or any of us. They will prostitute you for all you are worth, and cleverly make you think its what YOU wanted.
"And when you end up in rehab as a result of being prostituted, ‘they’ will be sunning themselves on their yachts in Antigua, which they bought by selling your body and you will find yourself very alone."
Sinead is also firm in telling newly single Miley that she shouldn't thrive off male attention.
She writes: "None of the men oggling you give a s**t about you either, do not be fooled. Many’s the woman mistook lust for love.
"If they want you sexually that doesn’t mean they give a f**k about you. All the more true when you unwittingly give the impression you don’t give much of a f**k about yourself.
"And when you employ people who give the impression they don’t give much of a f**k about you either. No one who cares about you could support your being pimped.. and that includes you yourself."
Sinead goes on to tell Miley she's "worth more" than her sex appeal in this "dangerous world".
She adds: "Don’t be under any illusions.. ALL of them want you because they’re making money off your youth and your beauty.. which they could not do except for the fact your youth makes you blind to the evils of show business.
"If you have an innocent heart you can’t recognise those who do not."
Though Sinead is obviously a fan of Miley's music, she doesn't like the way the young star has gone about her image overhaul.
She says: "As for the shedding of the Hannah Montana image.. whoever is telling you getting naked is the way to do that does absolutely NOT respect your talent, or you as a young lady.
"Your records are good enough for you not to need any shedding of Hannah Montana. She’s waaaaaaay gone by now.. Not because you got naked but because you make great records."
Sinead concludes: "The message you keep sending is that its somehow cool to be prostituted.. it’s so not cool Miley.. It’s dangerous. Women are to be valued for so much more than their sexuality. We aren’t merely objects of desire.
"I would be encouraging you to send healthier messages to your peers.. that they and you are worth more than what is currently going on in your career. Kindly fire any motherf***er who hasn’t expressed alarm, because they don’t care about you."
