Miley Cyrus responds to motherly advice by calling Sinead O'Connor crazier than a shithouse rat

The last time we checked YouTube, Sinead O’Connor didn’t spend a lot of time in her “Nothing Compares 2U” video fellating sledgehammers and grinding her naked ass onto wrecking balls. Despite that, the Irish singer—and part-time anal acrobat—was evidently a huge inspiration for Miley Cyrus, to the point where the former Miss Hannah Montana decided to pay homage with her latest video.

Apparently, “Wrecking Ball” isn’t, despite all appearances, a designed-to-titillate boobs-and-ass showcase. Instead, as Cyrus recently told Rolling Stone, it’s meant as a modern tribute to “Nothing Compares 2U”, which found O’Connor shedding giant crocodile tears back in the days when MTV played videos, as opposed to Teen Mom 3 reruns.

That connection was evidently brought to the attention of O’Connor, who has responded by sending Cyrus an open letter.

In the letter, which can be viewed here, the former alt-icon, who refused to play by the major-label rules back in the day, declares that she’s offering Cyrus some motherly advice.

She starts out with: “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.”

Highlights from there, include: “The music business doesn’t give a shit about you, or any of us. They will prostitute you for all you are worth”; “None of the men ogling you give a shit about you either”; and “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.”

Montana has responded by Tweeting that O’Connor, who has a history of mental health problems, is crazier than a shithouse rat. As you'll see below, she screen-grabbed some of the singer's past Tweets asking for psychiatric help, and then pasted them along with “Before Amanda Bynes.... There was....”

(Actress Amanda Bynes is currently in a hospital receiving psychiatric help).

Cyrus then reportedly whipped off all of her clothes and then pole-vaulted onto the business end of a pneumatic sledgehammer retro-fitted with a Coney Island Wife-Tamer-brand dildo.
