Waitress Steps Forward as Tiger Woods' Alleged Mistress

While Rachel Uchitel is denying an affair with Tiger Woods, a 24-year-old Los Angeles cocktail waitress is coming forward to reveal details of her and the golfer's illegitimate hookup.

In an upcoming issue of Us Weekly, Jaimee Grubbs has revealed that her and Woods have been seeing each other since she was 21. She claims she's had 20 sexual encounters with Woods, and has 300 text messages and photos to prove it.

Us Weekly plans to post private voicemail messages from Woods to Grubbs, on their site Wednesday.

On Monday, Woods addressed the car accident and media suspicions on his website, stating, "This situation is my fault, and it's obviously embarrassing to my family and me. I'm human and I'm not perfect. I will certainly make sure this doesn't happen again... This incident has been stressful and very difficult for Elin, our family and me. I appreciate all the concern and well wishes that we have received. But, I would also ask for some understanding that my family and I deserve some privacy no matter how intrusive some people can be." --Linda Hobbs
