Mariah Carey's brother is terrified his image-obsessed sister will retaliate for revealing her "darkest secrets," RadarOnline.com has exclusively learned.
The "Hero" singer's siblings exposed those secrets in a series of blockbuster interviews — revealed first by Radar. According to her older brother, Morgan, and HIV-positive sister Alison, Grammy winner Mariah was subjected to devil-worshipping rituals as a child — and she endangered her twins by boozing!
Now Morgan is living in Italy, where he fears for his life after publicly complaining Mariah has abandoned the family following heroin addict Alison's prostitution bust.
As for 46-year-old Mariah's potential revenge, Morgan said: "It's about protecting this fiction…this image that she has created. It's about keeping the darkest secrets covered up."
As Radar reported, Mariah's bizarre behavior and addiction to booze and prescription pills stem from the peculiar antics of her mother, 79-year-old former opera singer Pat.
Pat subjected both daughters to "horrible" and "evil" satanic rituals, Morgan and Alison revealed.
Mariah's sibling also alleged she was boozing it up while pregnant with twins, Moroccan and Monroe, now 5, and after they were born.
Shockingly, Morgan claimed, Mariah handed him several bottles of wine covered in a blanket, and ordered him to "get rid of it!" when he visited her in the maternity ward.
"It's a chronic behavior she absorbed and learned from Pat," Morgan told Radar. "My worst fear is that she'll die just like Whitney Houston."
