Mariah Carey’s brother has blasted her "vindictive nature". The 'Fantasy' singer is being sued by Morgan Carey for defamation and the intentional infliction of emotional distress after he claimed she featured "malicious falsehoods" about him in her memoir 'The Meaning of Mariah Carey', but in her response, the 51-year-old star insisted it was in the public interest for her to share stories of her troubled childhood in order to inspire others.
