Cardi B’s younger sister Hennessy has passed away due to Alcohol Poisoning. Cardi B must be devastated. Hennessy was last seen with Cardi after going out on Friday night, Dec 23rd, at 9:31 they were seen walking into the club, at 1:37 they were seen coming out, drunk, and nauseous. Cardi says she was sober enough to drive home. Bad idea. But Cardi dropped Hennessy off at home and Hennessy was seen walking into her house around 2:24 and was never seen after that, Cardi was worried and went over and found her unconscious later to find out that she passed away the night before.
