Similar to the first two cycles, the third season of "Celebrity Rehab with Dr. Drew" will follow the real-life experiences of celebrity patients undergoing detoxification and treatment at The Pasadena Recovery Center. The show will follow Mackenzie Phillips (One Day At A Time), Heidi Fleiss, Tom Sizemore, Dennis Rodman, Mindy McCready (Country Music Singer), Lisa D'Amato (ANTM), Mike Starr (Alice in Chains), Joey Kovar (Real World Hollywood) and Kari Ann Peniche (Playboy Playmate).

The series will chronicle the patients' intensive 21-day program with both group and one-on-one therapy and non-traditional therapies like art and music. Returning to the show to help Dr. Drew are drug counselor Bob Forrest and resident technician Shelly Sprague who have each spent years on both sides of the rehab fence. Dr. Drew is also bringing in some additional prominent physicians to help him give the patients supplementary one-on-one care.

Dr. Drew, who is a highly respected practicing MD and is board certified in addiction medicine, will once again give viewers an unflinching look at exactly how the rehab process works and what it feels like for participants. Dr. Drew hopes to use his celebrity patients to humanize the process and show viewers that treatment is a viable way to break the cycle of addiction.
