NEW YORK (CBS) Three new stars have signed on to undergo "Celebrity Rehab."
Former Tiger Woods mistress Rachel Uchitel, actor Jeremy London and former model Janice Dickinson have all signed on to appear on the fourth season of "Celebrity Rehab with Dr. Drew," VH1 announced on Sunday.
The three will join "The Hills" troublemaker Jason Wahler, former teen idol Leif Garrett, Frankie Lons (the mother of singer Keyshia Cole), and oil heir Jason Davis, according to E! Online.
Filming for the show's fourth season had been postponed, according to the report, because producers couldn't lock down a strong enough cast.
The stars will undergo 21 days of detox and treatment at the Pasadena Recovery Center, and episodes are set to premiere later this year.
Last week, it was reported that Uchitel was also being considered for a spot on NBC's "Celebrity Apprentice."
