Tiger Woods Alleged Mistress, Rachel Uchitel, Cancels Press Conference

A potentially explosive news conference with an alleged mistress was canceled and more details trickled out about the car accident that started all the trouble for Tiger Woods.

The news conference in Los Angeles for Rachel Uchitel, the woman who denied a tabloid report about an affair with Woods, was canceled about an hour before it was to begin Thursday.

Tiger Woods did not pay purported gal pal Rachel Uchitel to cancel her expected dish-all news conference.

She backed out because she was "scared for her safety," sources told the celebrity gossip website TMZ.
