A host of stars including Janice Dickinson and Jeremy London have signed up for the fourth installment of VH1’s “Celebrity Rehab with Dr. Drew,” VH1 has announced.

The cast will also include troubled former “Laguna Beach” star Jason Wahler, oil heir Jason Davis, Frankie Lons, who is Keyshia Cole’s mother and ‘70s teen idol Leif Garrett. In an unexpected move, also joining the fray is Rachel Uchitel, the alleged former mistress of Tiger Woods. She was billed by VH1 in a press release as an “Infamous Party Planner.”

The group will shortly be checking into the Pasadena Recovery Center, where they will complete a 21-day program under the supervision of Dr. Drew Pinksy. VH1 has not yet set an airdate for the project, but it is expected to hit television screens later this year.

It is unclear what London will be treated for, however, last month, the former “Party of Five” star claimed he was kidnapped while he was fixing a flat tire, and forced to take drugs. He later sought an injunction against his family members to stop them from giving interviews. A judge rejected his request, noting that comments made by the actor’s family were covered under the First Amendment, the Associated Press previously reported.

Wahler and Garret have had a long history of run-ins with the law due to substance abuse problems.

According to TMZ, former supermodel Janice is expected to tackle alcohol issues. Meanwhile, a source told Us Weekly that Uchitel will tackle love issues.

“Rachel is addicted to love,” a source told the mag.
