Did the tweets that Miley Cyrus posted about Sinead O’Connor result in the Irish rocker being cyberbullied? The ‘90s singer posted a fourth (and likely final) open letter about their social media war, declaring that she was a victim of cyberbullying due to the conflict. Cyrus posted old tweets that O’Connor wrote on Twitter two years ago about attempting suicide, but the Irish singer said that Cyrus’ attempts at mockery resulted in real-life harassment from her Twitter followers, who urged O’Connor to actually commit suicide.

In the open letter O’Connor wrote: “As a result of what you did I have had numerous communications from people urging me to commit suicide. Not to mention I have been the subject of literally thousands of abusive articles and or comments left after articles, which state that I and therefore all perceived mentally ill people, should be bullied and be invalidated.”

The ‘90s singer complained Cyrus’ comments about her being unstable have affected her career. “It is extremely hard to get employment when people think one is in mid-breakdown,” she wrote. “I now have to have management write to half the show business world to explain my tweets were two years old and that in fact I am very fit for work. I have four children to support. I can’t do that if people believe me to be unemployable.”

The controversy started last week when O’Connor posted an open letter uring Cyrus to tone down her overly sexual image and stop “prostituting” herself for the music industry. Cyrus previously said O’Connor’s hit song “Nothing Compares 2U” was an inspiration for her “Wrecking Ball” video. In response Cyrus reposted O’Connor’s old suicide tweets and wrote: “Before Amanda Bynes…there was…”

O’Connor was outraged, saying she would file a lawsuit unless the tweets were removed. Cyrus hasn't yet done this, but no lawsuit has been publicly filed. "Have you no sense of danger at all? or responsibility? Remove your tweets immediately or you will hear from my lawyers,” she wrote. "I am certain you will be hearing from all manner of mental health advocacy groups also. It is not acceptable to mock any person for having suffered."

While Cyrus seems to have officially moved on from her feud with O’Connor, she surprisingly began a new Twitter battle with Today show host Matt Lauer. When Lauer asked about her hyper-sexual image and whether it was a phase, Cyrus said: “Well, I heard when you turn 40, things start to go a lot less sexual. I heard that’s when people don’t have sex anymore.” When the Today host revealed that he’s 55, the “Wrecking Ball” singer quipped: “Oh, well then you’re really, definitely not sexual.”
