I saw a post the other day referencing Miley Cyrus' disgusting tweets about Sinead O'Connor and never knew that O'Connor had penned this open letter to Cyrus just a day (days?) before those tweets.

Here's the letter in full:

Dear Miley,

I wasn’t going to write this letter, but today i’ve been dodging phone calls from various newspapers who wished me to remark upon your having said in Rolling Stone your “Wrecking Ball” video was designed to be similar to the one for “Nothing Compares” … So this is what I need to say … And it is said in the spirit of motherliness and with love.

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 its the music business or yourself doing the pimping.

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. I am happy to hear I am somewhat of a role model for you and I hope that because of that you will pay close attention to what I am telling you.

The music business doesn’t give a s*** 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.

None of the men ogling you give a s*** 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*** about you. All the more true when you unwittingly give the impression you don’t give much of a f*** about yourself. And when you employ people who give the impression they don’t give much of a f*** about you either. No one who cares about you could support your being pimped … and that includes you yourself.

Yes, I’m suggesting you don’t care for yourself. That has to change. You ought be protected as a precious young lady by anyone in your employ and anyone around you, including you. This is a dangerous world. We don’t encourage our daughters to walk around naked in it because it makes them prey for animals and less than animals, a distressing majority of whom work in the music industry and it’s associated media.

You are worth more than your body or your sexual appeal. The world of showbiz doesn’t see things that way, they like things to be seen the other way, whether they are magazines who want you on their cover, or whatever … 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.

I repeat, you have enough talent that you don’t need to let the music business make a prostitute of you. You shouldn’t let them make a fool of you either. Don’t think for a moment that any of them give a flying f*** about you. They’re there for the money… we’re there for the music. It has always been that way and it will always be that way. The sooner a young lady gets to know that, the sooner she can be REALLY in control.

You also said in Rolling Stone that your look is based on mine. The look I chose, I chose on purpose at a time when my record company were encouraging me to do what you have done. I felt I would rather be judged on my talent and not my looks. I am happy that I made that choice, not least because I do not find myself on the proverbial rag heap now that I am almost 47 yrs of age … which unfortunately many female artists who have based their image around their sexuality, end up on when they reach middle age.

Real empowerment of yourself as a woman would be to in future refuse to exploit your body or your sexuality in order for men to make money from you. I needn’t even ask the question … I’ve been in the business long enough to know that men are making more money than you are from you getting naked. Its really not at all cool. And its sending dangerous signals to other young women. Please in future say no when you are asked to prostitute yourself. Your body is for you and your boyfriend. It isn’t for every spunk-spewing dirtbag on the net, or every greedy record company executive to buy his mistresses diamonds with.
