Sinead O’Connor has took to her Facebook to blast Miley Cyrus, after the Twerk Team Captain mocked her breakdown and compared her to Amanda Bynes. Before the feud, Miley bigged up Sinead in a Rolling Stones magazine interview and said her “Wrecking Ball” video was inspired by the 90’s singer’s “Nothing Compares 2 U” video. O’Conner’s first letter to Cyrus expressed her concern for the pop star, saying that Miley was letting herself be “prostituted” by the music industry. OUCH!
