Rachel Uchitel on Celebrity Rehab: I Quit!

Declaring "I quit" and running away from the set, Rachel Uchitel apparently couldn't handle the intense pressure of Celebrity Rehab with Dr. Drew. Instead, Tiger Woods' mistress checked into a swanky hotel. "After a very intense day of filming, Rachel couldn't handle being at the Pasadena Recovery Center" and left, according to a Radar Online source. Rache fled for Beverly Hills' L'Ermitage Hotel after an intense day with Dr. Drew, during which she "had trouble coping with the issues" discussed. We reported in recent weeks that Uchitel is being treated for "emotional issues" (i.e. banging married celebrities) as well as an addiction to pills. She was discussing her issues with self-esteem and self-worth, along with her addiction to Ambien when absolutely lost it and bolted the set. Rachel Uchitel flaked on Celebrity Rehab 4 ... but will she be back? Producers located Uchitel the next morning. "Producers arrived at the hotel the following morning, and calm prevailed," says an inside source. "Rachel simply needed some time away from the intense pressure and scrutiny she is dealing with. She agreed to go back to Celebrity Rehab." "Rachel has never had to face these kind of issues like this before, and talking about it pushed her over the edge, and her instinct was to run." Well, sure. Of course, Rachel isn't legally allowed to talk about her affair with Tiger Woods, but the world's #1 golfer looms large in her life. “Her issues go beyond Tiger, but he was the catalyst that pushed her over the edge," a close source said of the 35-year-old "VIP hostess." No word if she'll talk about David Boreanaz.Wesley Snipes Sandra Bullock Bruce Willis Britney Spears
