Tiger's Whore Goes Into Actual Rehab

What did serial mistress Rachel Uchitel do after she finished filming Celebrity Rehab?
She checked into real-life rehab. You know, the kind without cameras and microphones.
Uchitel checked into a transitional living facility in Malibu to help stop her addiction to drinking, smoking, and pill-popping
Sources say she’s spending over $20,000 to stay there for 30 days – with her dogs.
$20,000??? Is she using Tiger‘s hush money to get straight??
