Miley Cyrus has revealed that she was unaware of Sinéad O’Connor’s mental health during their infamous verbal feud. In 2013, O’Connor raised concerns about Cyrus’s ‘Wrecking Ball’ music video through an open letter. Cyrus responded by mocking O’Connor in an interview and on social media. However, in her recent Hulu special, Cyrus reflects on the past feud and acknowledges her lack of awareness regarding O’Connor’s battles with mental health. This revelation comes as Cyrus releases her latest single ‘Used to Be Young,’ exploring her personal growth.
