For some odd reason, Miley Cyrus posted a picture yesterday, October 3rd, of two-year-old tweets from '90s star Sinead O'Connor, who at the time was suffering a public meltdown and was publicly seeking psychiatric assistance.  Miley may have been responding to Sinead's open letter to her on her Facebook account, in which she expressed her concerns about Miley's behavior.

The tweet that Miley posted read, "Before there was Amanda Bynes...There was (O'Conor)," followed by the screen shot of Sinead's alarming tweets.  

During a recent interview with "Rolling Stone," Miley told the magazine that her "Wrecking Ball" video was in fact inspired by O'Connor's 1990 video for her single "Nothing Compares 2 U," which only makes Miley's random mockery even more surprising.

Sinead didn't take too kindly to Miley's slander, as it became widely believed by the general public that the tweets were recent and that Sinead's mental state was again unstable.  Sinead posted a few public letters in response to Miley on her Facebook account expressing her own concerns for Miley's wild behavior, but also said that she would be having her lawyers contact Miley's because she doesn't at all appreciate mocking Amanda Bynes, herself, or anyone else who has suffered from mental illness.  Miley didn't respond with an apology, but instead posted a picture of Sinead tearing apart a picture of Pope John Paul II on October 3rd, 1992 when she was featured on "Saturday Night Live."

Sinead felt as though Miley was sending further jabs at her over her past mental illness issues and posted one more letter on her Facebook airing out Miley even more.  She offered her the opportunity to apologize, but Miley refused, and said so directly on Twitter with yet another mocking series of tweets. 

Check out all of the back-and-forth drama above.  Do you think Sinead will in fact seek legal action against Miley Cyrus for bullying?
