Mariah Carey Siblings: Singer's Brother Blasts Her For Not Helping With 'Dying' Sister's Medical Bills [VIDEO]

Mariah Carey’s family issues goes beyond her ongoing divorce with her estranged husband, Nick Cannon.

Now, the diva’s brother, Morgan, is calling her out for not assisting her sister, who is said to be dying, with her medical bills. The woman, Alison, is living with HIV and Morgan didn’t mind blasting Mariah in The Sun about their family woes.

“She probably spends more on dog food than it would cost to make sure her sister gets properly cared for.”

He pointed out a time when he reached out to Mariah to inform her that he and his wife suffered a miscarriage, but she never responded.

“But that’s typical,” he added. “Because the world has to revolve around Mariah and there is no room int he world apart from her.”

He continued with a message for Mariah.

“Your sister is dying and she is struggling and where are you? You think you are so fabulous…”

Alison is waiting to get brain and spine surgery.

She even called out Mariah at one point after she said she hoped to meet Mariah and Cannon’s twins Moroccan and Monroe. They are now five and it's safe to say Alison has yet to meet them.

Morgan continued and said that Mariah has been MIA for much of Alison’s medical battle.

“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. [Mariah] didn’t even show up at the hospital."

He said despite that Alison was able to recover, but is still in need of an operation.

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

Mariah is currently planning a wedding to her billionaire fiancee, James Packer.
