Jeremy London, Janice Dickinson, Jason Wahler To Enter ‘Celebrity Rehab’

Tiger Woods mistress Rachel Uchitel, '70s star Leif Garrett also join season four of VH1 show.

It will be a mix of mistresses, models, moms, reality stars and former child actors on the upcoming season of VH1′s “Celebrity Rehab.”

The MTV sister network announced the cast for the latest go-round of the Dr. Drew Pinsky-led show, which will feature Tiger Wood mistress Rachel Uchitel, police blotter regular and former “Hills” cast member Jason Wahler, ex-supermodel Janice Dickinson (“America’s Next Top Model”), troubled actor and alleged recent kidnap victim Jeremy London (“Party of Five”), former teen pop star Leif Garrett, socialite and oil heir Jason Davis and Frankie Lons, the mother of singer Keyshia Cole.

The cast will soon check into the Pasadena Recovery Center for season four of the show, which is expected to air before year’s end in eight hour-long episodes. As it has before, the show will take viewers through the intense 21-day program, in which the celebs will undergo both group and one-on-one therapy and share their experiences struggling with drugs and alcohol with viewers.

Party planner Uchitel has grabbed headlines over the past year thanks to her involvement in the Tiger Woods infidelity scandal. She is also slated to appear in Playboy magazine and on “Celebrity Apprentice.” Dickinson, who calls herself the “first supermodel,” was a cast member on VH1′s “The Surreal Life” and the UK reality show “I’m a Celebrity … Get Me Out of Here!” She starred in “The Janice Dickinson Modeling Agency” and has talked publicly about her abusive father.

London, 37, has starred in shows such as “Party of Five” and “7th Heaven” and the Kevin Smith movie “Mallrats.” He has struggled with drug and alcohol addiction and recently grabbed headlines after claiming that he was kidnapped in Palm Springs, California, and forced to do drugs and buy alcohol.

Former “Hills” and “Laguna Beach” cast member Wahler has racked up a series of DUI and assault arrests and entered rehab in 2008 after punching a truck driver in the face. Though a ’70s teen heartthrob thanks to some pop hits, appearances on TV shows including “Wonder Woman” and “CHiPs” and movie roles in “Walking Tall” and a notoriously cheesy adaptation of the Beatles’ Sgt. Pepper’s Lonely Hearts Club Band album, Leif Garrett is best known these days for a series of arrests on drug charges . He was nabbed in February for possession of black tar heroin in Los Angeles.

Davis, sometimes referred to as “Gummi Bear,” is one of the heirs to a billion-dollar oil fortune and a tabloid staple. The least known cast member is Lons, mother of Keyshia Cole, who has struggled in the past with drugs and alcohol while trying to raise her seven children.
