The second season of Celebrity Rehab doesn't really have very well-known celebrities. For example, Rod Stewart's son Sean is there, as is Rodney King, Nikki McKibbon (from the first season of American Idol), the first drummer of Guns 'N Roses (who was booted from the band for doing too many drugs, if that's possible), and a model/actress named Amber Smith, who I hadn't heard of before. Amber's been addicted to a number of pills for years, thanks to her mother, and supported both of them with her career until their drug habits blew through her money and they were forced to live in a Hollywood motel.
