Miley Cyrus may have landed her bare a** in hot water.

Just today, Sinead O' Connor, a legend in the music industry wrote a third open letter to Miley Cyrus. After writing two open letters to the "Wrecking Ball" singer it seems that Miley too respond in a rather disrespectful manner by bring about Sinead O' Connor's mental health in the past. She had also mentioned Amanda Bynes who is currently undergoing treatment in rehab for Schizophrenia. Cyrus had taken a screenshot of Sinead O'Connor's tweets seeking help about her problems and posted a tweet saying:

"Before Amanda Bynes.... There was...." It was posted at 8:53AM yesterday Oct 3.

Just today, Sinead O'Connor wrote a third letter and this one did not seem heartwarming towards the singer. In her letter to Cyrus, the Irish singer demanded for a public apology towards her and to Amanda Bynes and to all the mentally ill women out there that Miley disrespected and if she did not do this Sinead would take this to court and file a case against Cyrus.

Cyrus had responded to Sinead's first open letter posting it in her twitter account:

"Sinead. I don't have time to write you an open letter cause Im hosting & performing on SNL this week, So if youd like to meet up and talk lemme know in your next letter. :)"

Part of the letter from her facebook page, where you can read the whole letter, Sinead wrote saying:

"You have no business abusing Amanda Bynes or anyone else. How do you think you made her feel yesterday? How do you feel when your friend Britney Spears is mocked and humiliated for having had mental health problems? I know I personally want to bash those who treat her that way. If she is your friend and more importantly if you are a true friend to her.. you ought apologise for joining those who mock and humiliate women who have been too nice frankly, to manage the music business without sensibly losing their minds."

She had also written in her letter saying:

"Cease behaving in an anti-female capacity. You will become the victim of it shortly. Soon it will be you the media 'crazy' .. and you will not enjoy it.. and you will appreciate people (like myself) standing up for you. Which I will be happy to do.. if you earn my respect today by apologising publicly."
