Miley Cyrus' singing career skyrocketed seemingly from the wild persona she adopted after her infamous VMA performance in August.
The 20-year-old singer's two most recent singles, "Wreaking Ball" and "We Can't Stop" landed the No. 1 and No. 2 positions, respectively, on Billboard's Hot 100. Cyrus' 2009 single "Party in the U.S.A." was her only other top 5 hit, peaking at No. 2 on Billboard.
While many artists -- mostly rappers -- embrace Cyrus' antics, '80s Irish singer Sinead O'Connor has some motherly advice for the former Disney star, and she expressed it in an open (and very blunt) letter.
O'Connor posted the letter to her website on Thursday, one day after Cyrus' documentary aired on MTV.
"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," she wrote.
"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."
O'Connor explained that she didn't want to write the letter, but felt it was necessary after reading in Rolling Stone that her 1990 cover of Prince's "Nothing Compares 2 U" inspired the design of Cyrus' "Wreaking Ball" video.
"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."
While O'Connor continues her letter by telling the "Hannah Montana" star that men who lust over her don't actually care for her, she acknowledges the young singer's talent.
"You have enough talent that you don't need to let the music business make a prostitute of you," she wrote. "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."
Cyrus quickly went on the defencive in a set of frivolous tweets, where she compares O'Connor to Amanda Bynes.
