Two alleged mistresses of Tiger Woods, Rachel Uchitel and Jamie Grubbs, almost ran into each other in California.

According to a spy at Rande Gerber's Caf
é Habana in Malibu, Grubbs, Los Angeles cocktail waitress, came in for lunch the other day with an unidentified man.

Right after they left, Uchitel came in with a group of friends who were all drinking, but she abstained.

Maybe she's keeping it sober after her stint on "Celebrity Rehab," reports the New York Post. (ANI)
