Miley Cyrus' Tweets Anger Sinead O'Connor
Sinead O'Connor has demanded an apology from Miley Cyrus after the American star appeared to mock the Irish singer's mental health problems.
O'Connor had earlier posted an open letter to Cyrus on her website in which she expressed her concern that the former Hannah Montana star was allowing herself to be "prostituted" by the music industry.
But Cyrus responded by posting a screenshot of tweets from 2012 in which O'Connor, who has bipolar disorder, asked followers to recommend a psychiatrist.
She also compared the Irish singer with former child actress Amanda Bynes, who is currently undergoing psychiatric treatment.
O'Connor accused Cyrus of "irresponsible" behaviour and told her to "remove your tweets immediately".
In two follow-up open letters to Cyrus on her website, she said: "You mock myself and Amanda Bynes for having suffered with mental health issues and for having sought help.
"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.
"I hope that you will apologise to Amanda Bynes and to any person who has been wounded by your mockery of those who have suffered."
The row began after Cyrus claimed in Rolling Stone magazine that the video for her Wrecking Ball song was modelled on O'Connor's Nothing Compares 2 U, where she sheds a single tear.
However, O'Connor expressed her concerns that the former child star was being exploited, with the video also showing her licking a sledgehammer and writhing naked on a swinging metal demolition ball.
The 46-year-old said: "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."
But Cyrus dismissed her offer of help, tweeting: "Sinead. I don't have time to write you an open letter cause I'm hosting & performing on SNL (US comedy show Saturday Night Live) this week."
O'Connor has also written an open letter to Bynes offering her support.
"I wish to send you some words of love and encouragement as I have just discovered you are currently in rehab because of a similar medical condition to my own," she wrote.
