Of course we knew back in the day that Mariah Carey’s sister was on drugs and was arrested for prostitution… but now we're hearing that Mariah’s sister Allison is now HIV positive and an escort. The folks over at Bossip are saying that Allison is so desperate for cash, she’s selling herself as an “adult escort.” Allison charges $250 for house calls!!!

Mariah has helped Alison in the past with trips to rehab, but as of now Alison is cut off financially which has resulted in her turning tricks to make a buck. For her part, Alison says she provides body rubs and companionship.

We hope she leaves the "excort" business and seeks medical treatment.
