Earlier this month, all-around showman Nick Cannon had a bit of an embarrassment on his hands when his brother Gabriel was arrested for allegedly robbing and assaulting a man and his teen son who he had been working with on a reality show. Of course, Nick isn't the only celebrity to have an embarrassing sibling, and ironically his songbird wife, Mariah Carey, also has a sibling who has been in trouble with the law.

Alison Carey Scott is a 49-year-old former drug addict and alcoholic who has been HIV positive since the 1990s. She's also been arrested for prostitution and is still offering herself as an "escort" on websites.
