Mariah Carey?s older brother Morgan, 51, a former model and fitness trainer, says, ?she thinks the world revolves around her? and he desperately wants Mariah to help their ailing sister.

?Your sister is dying and she?s struggling and where are you?? Morgan wants to know.

?You think you are so fabulous, but you are an evil witch.? Mariah, ?is only in love with herself and her $5 million engagement ring,? he claims.

Mariah, whose fortune is estimated at $520 million, is engaged to Aussie billionaire James Packer.

Morgan, who has given several less-than-brotherly interviews about Mariah over the years, added that he believes his selfish sister cares more about her Jack Russell terriers, Cha Cha and Jill E. Beans, than she does her own flesh and blood.

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

Mariah’s sister Alison, 54, reportedly has a checkered past. Alison became pregnant at 15, had three more kids, then turned to prostitution to fund a drug habit.

Alison and Mariah had a falling out in 1994, and when Alison was diagnosed with HIV, she threatened to cash in by writing a tell-all book about her celebrity sister. The two have not spoken in many years.

Morgan reports that Alison nearly died in Hawaii in late 2015 but has since recovered. However, she still needs surgery and Morgan believes Mariah is ?intentionally leaving their sister out to dry.? (source)

In addition, Morgan feels that Mariah has the means to ?put our sister in a good hospital? and get her ?the care she needs,? but despite he and Alison reaching out to their famous sibling ?over and over again,? he said the they never hear back from Mariah.

Meanwhile, Morgan has decided to blast the famous singer publicly, and Mariah still has not made any comments regarding brother?s very public outburst.
