Alison Carey is Mariah Carey’s sister.
She is also a former prostitute who is HIV positive.
The sisters have had an estranged relationship since 1994, a year after her wedding to Tommy Mottola.
Now, her sister has made a desperate video plea to Mariah, asking for her help.
“Mariah I love you and I desperately need your help. Please don’t abandon me like this,” she says in the video obtained by the Daily Mail.
Earlier this month, their brother Morgan told The Sun that Mariah was “evil” for not helping provide for Alison’s health care.
“Your sister is dying and she is struggling and where are you? You think you are so fabulous, but you are a witch,” Morgan said.
Morgan fell out with his sister after allegedly advising her to be careful of ex-husband Nick Cannon.
“Nick listened to people who said, ‘Get with Mariah, she thinks you’re cute, have kids and ride it to the bank’,” Morgan has said.
“Nick was there for the cash from day one. He doesn’t give a damn about Mariah.”
Morgan also doubted whether Mariah was in love with fiance James Packer or just the billionaire’s money.
“I don’t even think Mariah is in love with James, she’s only in love with herself. She is evil,” he said.
“She has always been that way. It’s her $7 million engagement ring she is in love with.
“It is so tragic that while she is out flashing her big diamond ring to anyone who will pay attention, she can’t lift a finger to help her dying sister,” he said.
