Mariah Carey and Nick Cannon Divorce Updates: Depressed Diva's Brother Fears for Her Life

Mariah Carey's brother Morgan is worried about his sibling's health and fears that she might "die like Whitney Houston."

While Morgan has not directly spoken to his sister in over 2 years, he claims that he has never seen the 'Hero' singer sober.

He feels that Mariah is trying to drown her sorrows by talking to the bottle and as a result is unable to look after her four year old twins. She I also taking a number of medications on a daily basis which includes Ativan, Zyprexa and Depakote.

Morgan goes on to say that Mariah had drinking problems since 2001.

He said, ''Mariah was drinking through her pregnancy -- even while she was nursing.

''I can't say that I have ever been around her when she was sober, and that's very scary.''

''She does not have a support system, and she is not mentally capable.''

He also feels that Mariah has ''pushed away the only people who've been trustworthy'' and would eventually resort to blaming her entourage if something happens to her.

He said: ''If my sister turns up dead ... I'm not going to look the other way! Anyone who's filling her glass is jeopardising her life!''

Morgan also didn't mince words while speaking about her sisters estranged husband Nick Cannon, calling him a ''crock of s**t" and thinks he is only interested in her money.

''Nick listened to people who said, 'Get with Mariah, she thinks you're cute, have kids and ride it to the bank.' Nick was there for the cash from day one. He doesn't give a damn about Mariah.

''Nick took tremendous advantage of her and continues to do so.''
