UPDATE: Miley Reacts To Sinead's Open Letter

With over 20 years in the music business, Sinèad O'Connor has plenty of advice to give and give it she did in an open letter to Miley Cyrus, but her words for the We Can't Stop singer weren't so well received.

The 46-year-old Irish singer-songwriter was compelled to reach out after seeing that Miley's Wrecking Ball video was inspired by the one for Sinèad's 1990 hit 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," Sinèad wrote. "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."

Miley, 20, responded on Thursday, Oct. 3, to the post, tweeting:

It should be mentioned that the screen grab that Miley took of a Twitter page is not the verified account of Sinèad, but according to Yahoo!, the singer did at one time use this handle. The former Disney star, who is hosting this weekend's Saturday Night Live, sent out another tweet about the singer:

O'Connor's letter goes on to say, "The music business doesn't give a sh*t about you, or any of us. They will prostitute you for all you are worth, and cleverly make you think it's 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."

Sinèad then suggested that Miley missed the mark on capturing the true spirit of the Nothing Compares video, writing, "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."

Still, Sinèad does praise the former Disney star for her "obvious" talent and leaves her with a somewhat uplifting message.

"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," she wrote. "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."
