On Nov. 24, Tiger Woods left a panicked voicemail on his mistress' cell phone -- the day before reports of his indiscretions with another woman first surfaced.
In an explosive voicemail obtained by Usmagazine.com, the golfer, 33, tells 24-year-old cocktail waitress Jaimee Grubbs, "Hey, it's Tiger. I need you to do me a huge favor. Can you please take your name off your phone? My wife went through my phone and may be calling you. So if you can, please take your name off that. Just have it as a number on the voicemail. You got to do this for me. Huge. Quickly. Bye."
In the new issue of Us Weekly (on stands Wednesday), Grubbs details their affair, revealing that they first hooked up in April 2007 when she was just 21 years old. She says they had 20 sexual encounters over a nearly three-year period.
She also has photos and more than 300 racy text messages from Woods, such as one that begins with "I will wear you out..."
"I loved how we got along," Grubbs tells Us Weekly. "But I knew, in the back of my mind, there could never be just us. There would always be the wife, or somebody else."
Woods wed Elin Nordegren, 29, in 2004; they are parents to daughter Sam, 2, and son Charlie, 9 months.
Woods' one-car crash near his Florida mansion early Friday morning reportedly happened after the couple got into a heated argument over his alleged affair with nightlife hostess Rachel Uchitel, 34.
