It all started when Sinead wrote a cautionary open letter to Miley expressing concern over her current artistic direction. It read, in part, "You will obscure your talent by allowing yourself to be pimped, whether it's the music business or yourself doing the pimping...You are worth more than your body or your sexual appeal. You have enough talent that you don't need to let the music business make a prostitute of you."
Instead of taking it to heart, Miley respnded by postings a few of O’Connor old Tweets discussing her mental health issues with the message, "Before Amanda Bynes.... There was...."

That prompted another, much angrier letter from Sinead. "Miley… Really? Who the [bleep] is advising you? Because taking me on is even more [bleepin'] stupid than behaving like a prostitute and calling it feminism."
Sinead, who took particular issue with Miley posting the old tweets, added, "You have posted tweets...which were posted by me when I was unwell and seeking help...In doing so you mock myself and Amanda Bynes for having suffered with mental health issues and for having sought help."
She goes on to demand an apology, and suggests that Miley "could really do with educating yourself, that is if you’re not too busy getting your [boobs] out to read."
Miley responded on her Twitter account with, "Sinead. I don't have time to write you an open letter 'cause I'm hosting and performing on SNL this week. So if you'd like to meet up and talk, lemme know in your next letter."
Sinead isn't interested -- at least not until Miley stops "behaving in an anti-female capacity." You can read her entire "next letter" HERE. Your move, Miley!
MILEY’S MOST GRAPHIC PHOTOS YET: Miley Cyrus continues to trash and burn her squeaky clean image. In her latest photo shot, the former Hannah Montana gets as naked as we've ever seen her.
In one picture, she's topless, wearing only lacy, see-through stockings on the bottom. She's holding her breasts in her hands, but letting her right nipple peek through her fingers. In another, her left breast is totally visible under a white, see-through top.
There are also a series of photos in which she's wearing a red, high-waisted leotard pulled up the crotch to reveal quite a bit of skin in that general area. Check them all out HERE.
IS BRITNEY SPEARS' RECORD COMPANY PRESSURING HER TO BE OVERTLY SEXY?: When BRITNEY SPEARS' "Work Bitch" video came out earlier this week, there was many a comment about how hot and sexy Brit looked and how racy the video was. Well apparently the original cut was way more risque than the finished product.
In a radio interview yesterday, Spears suggested that she's being pressured to be overly sexual. "Oh my God, we showed way more skin and did way more stuff for the video than what is actually there. I cut out half the video because I'm a mother and because, you know, I have children, " she said, responding to a question about how she feels about flaunting her body.
When asked directly if they're pushing her to go further than she wants to go Brit laughed somewhat uncomfortably before adding, quote, "Yes."
Meanwhile ... KATY PERRY thinks she's too old to be showing her body off in music videos. In a British radio interview, the 29-year-old Perry said "I don't know if I can pull that off any more. If I had Rihanna's body I would wear everything that Rihanna wears, because she looks fabulous in all of it."
Katy added that she would prefer people pay more attention to her songs and music than her outfits and lady parts.
