Photographer Terry Richardson posted a number of candid shots of Miley Cyrus from a recent photo shoot with the Wrecking Ball singer, on his blog on Oct. 3.

Cyrus is wearing a sheer top in one image, in another one she is seen topless exposing a nipple, and in most of the other shots she is wearing a skimpy leotard which reveals a lot of her crotch. She also toys with an Arizona ice-tea can, using it as phallic symbol in the pictures. The provocative images have inspired scathing comments from the Twitter-verse, including some from celebrities like Roseanne Barr and Chrissy Teagen.

"My vagina wouldn't stand for this," Teagen tweeted adding a link to a Perez Hilton post about the images.

Barr was a bit more direct. "YOU ARE BEING USED BY PIMPS. #listenupgirl #amandabynes was also abused," she wrote (the tweet has since deleted) 

In a recent feud between Cyrus and O'Connor, which started when O'Connor penned an open letter to Cyrus beseeching her to not allow the music industry and manipulative friends to pimp her out and expoit her, Cyrus lashed out by comparing the Nothing Compares to You Singer with Amanda Bynes.

Miley Cyrus compares Sinead O'Connor to Amanda Bynes in response to O'Connor's "Don't pimp yourself out" open letter.

O'Connor wrote another open letter to Cyrus in response to her vitriolic attack, posting it on Facebook on Oct. 4.

"Miley...Really?" O' Connor said in her second letter.

"Who the f--k is advising you? Because taking me on is even more f--kin' stupid than behaving like a prostitute and calling it feminism. You have posted today tweets of mine which are two years old, which were posted by me when I was unwell and seeking help so as to make them look like they are recent. In doing so you mock myself and Amanda Bynes for having suffered with mental health issues and for having sought help," she wrote.

Reiterating that she was being abused by the industry:

"It is most unbecoming of you to respond in such a fashion to someone who expressed care for you. And worse that you are such an anti-female tool of the anti-female music industry."

What could have been perceived as a cocky response or perhaps Cyrus actually didn't have time for intense sparring on the internet, the 20-year-old singer-songwriter quickly responded to O'Connor's second letter:

"Sinead. I don't have time to write you an open letter cause I'm hosting & performing on SNL this week," she wrote on Twitter.

Following that by asking O'Connor to meet her: "So if youd like to meet up and talk lemme know in your next letter. :)"

But O'Connor isn't backing down, she posted a third letter on Facebook on Friday, saying she wasn't interested in meeting the young pop star.

"I have no interest whatsoever in meeting you. You had plenty of time yesterday to abuse Amanda Bynes .. an entirely innocent party.. and myself.. who also did nothing to deserve your abuse.. along with every other sufferer of mental health problems and every person who suffered abuse at the hands of priests," she wrote.

O'Connor also held her accountable for mocking Bynes and herself, asking her to apologize:

"When you publicly apologise to Amanda and myself and all mental health sufferers as well as all who were abused by priests that will end the matter as far as I am concerned.

"What you did yesterday was designed to damage me and my career and has caused me enormous distress and harassment and has potential to damage my career, since you deliberately gave the impression those tweets of mine were not two years old but reflect my current condition. If you cannot apologize I will have no choice but to bring legal proceedings against you since it is extremely hard to be given work when people think one is suffering from mental illness."
