"Hey, it's Tiger. I need you to do me a huge favor," Woods says in the message. "Can you please, uh, take your name off your phone? My wife went through my phone and may be calling you. If you can, please take your name off that and, um, what do you call it, just have it as a number on the voicemail. Just have it as your telephone number. You have to do this for me. Huge. Quickly. Bye."
Grubbs claims to have some 300 text messages from Woods.
The waitress told US that she had not seen Woods for more than a year until October, when they met in Newport Beach, Calif.
"He gave me a huge hug and said, 'I've missed you. You look amazing,'" Grubbs told US. "We cuddled, watched 'Angels and Demons,' then had sex. It was very romantic."
Unlike Grubbs, Rachel Uchitel, the first alleged mistress has denied reports of an affair.
Named by the National Enquirer just days before a bizarre car accident outside his Florida home on Nov. 27, Uchitel denied the affair to the New York Post and mostly recently to OK! magazine.
Uchitel has denied rumors of an affair. She employed Gloria Allred, a California attorney famous for her high-profile clients.
"Not a word of it is true," Uchitel told the New York Post, about the allegations. "It's the most ridiculous story. It's like they are asking me to comment if there are aliens on Earth."
In the upcoming issue of OK!, Uchitel says: 'People have called me homewrecker, gold digger, tramp, whore. I make mistakes, but I'm not those things.
Uchitel began working in nightclubs, providing VIP services to the rich and famous, following her fiance's death on 9/11.
Siwik-Daniels is not the first porn star with whom the golfer is accused of cheating with. That distinction goes to Holly Sampson, 36, a busty blonde and Los Angeles resident.
Sampson, 36, a porn star featured in the films "OMG, Stop Tickling Me" and "Flying Solo 2" admitted to having sex with Woods at his bachelor party in an interview with the Web site Naughty America in May 2009.
Sampson said she was invited to have sex with the golfer after stripping at his bachelor party. Her lawyer Andy Contigulgia released a statement saying those comments were "truthful, accurate, and without any malicious intent" and that her "intimate" relationship with Woods occured beofre his marriage to Elin Nordegren.
Most of the women linked to Woods are models or work at some of the country's swankiest nightclubs, but Lawton, 33, who disclosed her alleged relationship to Britain's News of the World, worked for $8 an hour at a Perkins restaurant in Orlando.
"Sometimes I looked like a rag doll after we'd made love," she told the paper. "He really did like it quite rough. He wanted to spank me and loved pulling my hair as we had sex. He also liked me to talk dirty to him, but hair-pulling was what really turned him on.
For one year, beginning in 2006, Lawton said she and Woods regularly saw each for sex, partying at Orlando's Blue Martini club and having sex in the golfer's home and in his car parked in a church parking lot.
One of those backseat trysts was reportedly caught on film by photographers working for the National Enquirer in 2007. The story was quashed and the affair covered up when Woods agreed to appear on the cover of Men's Fitness, a title also owned by American media, in a quid pro quo with the publishing company, according to U.K.'s Mirror tabloid.
