Yesterday VH1 announced the new cast of celebrity rehab, which will include Rachel Uchitel and Jeremy London. Rachel Uthitel is a 35-year old party planner and the most prominent of Tiger Woods's mistresses and will be treated for pills. Party of Five and Mallrats's Jeremy London who has been in the spotlight since a bizarre incident last month where he claims to have been kidnapped by a group of men and forced at gunpoint to go on a 12-hour meth and ecstasy binge will also enter rehab for assorted substance abuses. Other participants in Season 4 will include former model Janice Dickinson, teen idol Leif Garrett and The Hills star Jason Wahler. The crew will undergo 21 filmed days and nights of detox at the Pasadena Recovery Center run by @DrDrew and the episodes will air later this year.
