The ‘most prominent’ of Tiger Woods’ mistresses, along with actor Jeremy London, along with "former model Janice Dickinson, former teen idol Leif Garrett and former ‘The Hills’ star Jason Wahler," have also signe up for VH1’s "Celebrity Rehab," Popeater reports.

The mistress is Rachel Uchitel, 35, who, according to the article, "will be treated not for sex addiction like her former lover, but for pills. What kind of pills is unknown."

According to the article, "London, of ‘Party of Five’ and ‘Mallrats’ fame, will enter Pinsky’s world of rehab presumably for assorted substance abuses. According to TMZ, his wife Melissa is also seeking treatment."
