Rachel Uchitel stormed off "Celebrity Rehab with Dr. Drew" about one week into shooting, claiming she could not make self-improvements while sharing a room with Janice Dickinson.
"I'm done being Janice's doormat," said Tiger Woods' alleged mistress. "And she's also preventing me from being able to do any sort of recovery."
Rachel joined the show hoping to get rid of her addiction to prescription medication, but grew tired of feeling belittled by the former model, saying, "I think she can just be rude because she thinks she's more important than everybody else here."
Watch the clip to see singer Leif Garrett re-live troubled childhood memories and actor Eric Roberts' physical breakdown. And watch "Celebrity Rehab with Dr. Drew" Wednesdays on VH1.
