Gary Busey by Eric Charbonneau/WireImage.com
As previously reported, VH1 is bringing back Celebrity Rehab with Dr. Drew for a second season of exploiting chronicling the struggles celebs face while detoxing in a treatment facility. But this time around, there's one huge reason to watch: Gary Busey.

Busey, whose wild antics have been well-documented (most recently his crazed behavior on the red carpet at the 2008 Academy Awards), is remarkably not one of the celebs in for treatment. Instead - touting 13 years of sobriety since his cocaine addiction - Busey will be a mentor to the new class of patients which includes Season 1 cast member Jeff Conaway ( Grease), Sean Stewart (son of music icon Rod Stewart), model/actress Amber Smith, Rodney King, Guns N' Roses' Steven Adler, Tawny Kitaen and former American Idol wanabe Nikki McKibbin. Here's hoping at least one of his sessions involves teaching the addicts how to yell at teenaged journalists.

The series will follow the patients during a 21-day program featuring group and one-on-one therapy sessions with Dr. Drew Pinsky and his team. VH1 is planning eight, one-hour episodes, which will begin airing this October. Will you be checking into Rehab? What kind of hijinks do you expect from Gary Busey? - Adam Bryant
