The 'Hero' hitmaker has been called "heartless" by her estranged older sibling Morgan Carey, who claims the 45-year-old singer has refused to pay for hospital treatment for their dying sister Alison.

He said: "She probably spends more on dog food than it would cost to make sure her sister gets properly cared for."

Alison - who is HIV positive and awaiting brain and spinal surgery - fell ill last year but has never heard from her famous sibling, despite "desperately reaching out" numerous times

Morgan slammed: "Your sister is dying and she is struggling and where are you? You think you are so fabulous, but you are a witch."

He then added to The Sun on Sunday newspaper: "Mariah needs to step up. I flew in from Hawaii last year when Alison was taken off a ventilator, believing she was going to die.

"My sister didn't even show up at the hospital.

"Alison has desperately reached out to Mariah over and over again. We never hear back."

Morgan hasn't spoken to his sister - who has four-year-old twins Moroccan and Monroe with second husband Nick Cannon - for over two years, but claims he has made repeated attempts to get in touch.

He said: "I told Mariah my wife had miscarried and she never even responded to that email either.

"But that's typical, because the world has to revolve around Mariah and there is no room in the world apart from her."

The 'Butterfly' singer's family claim they only found out about her recent engagement to James Packer through social media but don't expect to be invited to her wedding.

Morgan said: "I don't even think Mariah is in love with James, she's only in love with herself. She is evil.

"She has always been that way. It's her £5 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."
