'Celebrity Rehab with Dr. Drew' to return with Season 4

Despite reported problems with casting, "Celebrity Rehab with Dr. Drew" is set to return to VH1 later this year with its fourth season.

Like the first three seasons, the show will follow the real-life experiences of celebrity patients undergoing detoxification and treatment with Dr. Drew Pinsky at the Pasadena Recovery Center.

The fourth season's participants will include actor Jeremy London ("Party of Five," "7th Heaven"), Rachel Uchitel (Tiger Woods' former mistress), model and TV personality Janice Dickinson ("The Janice Dickinson Modeling Agency"), musician Leif Garrett, Frankie Lons (Keyshia Cole's mother), TV personality Jason Wahler ("The Hills") and socialite Jason Davis.

The series will chronicle the patients' 21-day program with group and one-on-one therapy. Returning to the show to help Dr. Drew are drug counselor Bob Forrest and resident technician Shelly Sprague.
