Tiger case new woman surfaces:

Plus, alleged NY mistress offers to take a lie detector test. Nike still stands behind golfer.

       *A new woman entered the Tiger Woods tabloid maelstrom Tuesday with claims that she had a 31-month fling with the golfer and has a voicemail and more than 300 text messages to prove it.
      
       Jaimee Grubbs, according to Us Weekly, claims she met Tiger in Las Vegas in April, 2007, when she was a 21-year-old cocktail waitress. Grubbs said she began a long-running affair with the athlete -- who married Elin Nordegren in 2004.

       Grubbs, who has appeared recently on VH1's "Tool Academy," claims to have had 20 sexual encounters with Tiger. Us Weekly, on newsstands today, has photos, racy texts from Tiger, and a voicemail from Nov. 24, in which Tiger suggests his wife might be on to the alleged affair.

       The new affair allegation came as the Florida Highway Patrol ended their investigation of Tiger's car crash outside his Orlando-area mansion last week without filing any criminal charges against him. He will, however, face a $164 fine and four points against his driver's license for careless driving.

  According to an accident report, Woods crashed his SUV into a fire hydrant and a tree at 2:25 a.m. Friday. The airbags did not deploy and Woods' wife told Windermere police she used a golf club to smash the back windows to help him out.
      
       Meanwhile, the former New York night club hostess alleged in a National Enquirer story to have had an affair with Tiger in Australia has called the allegations "ridiculous" and has offered to take a lie detector test to prove it.
      
       In an interview with the New York Post, Rachel Uchitel said of the report, "Not a word of it is true. It's the most ridiculous story. It's like they are asking me to comment if there are aliens on Earth."
      
       Uchitel said Woods had been to the New York City club where she worked, and she did escort Woods and his group in and out, but that was the extent of their contact.
      
       "I've always been the director of VIP services, that's my job -- to know these people, to have a relationship with them, to hang out with them.
It doesn't mean I'm having sex with them or an affair with them. ... But Tiger and I are not friends. That's a whole different ballgame. I've only met him twice," Uchitel told the Post. "I have never spoken on the phone with Tiger Woods, or texted him, ever. ... I do not have sex with celebrities, and I have not had an affair with Tiger Woods."
      
       "I told the [National] Enquirer and Star that it wasn't true. I told them not only did I have information to disprove the story, but I offered to take a lie-detector test."

       Woods' reputed affair with Uchitel was first reported by the National Enquirer, but the allegation spread when the report was linked to Woods' car crash -- an incident that Woods has so far refused to speak with police about.
      
       Uchitel blamed the rumors on an unidentified "acquaintance" who was seeking revenge against her and was allegedly paid $25,000 for her story.
      
       "She had a personal reason to make this up. She got herself invited on a trip that I went on [to Europe]. She conducted herself in a manner that was so embarrassing that the trip ended after a day. It was a total nightmare," Uchitel says of the woman. "I saw her again last week in Vegas.
I was embarrassed by her behavior. She fell down the stairs at the restaurant because she was so wasted. She's a train wreck."

 The car accident and the rumors surrounding it have not deterred Tiger's sponsor Nike from continuing to back him.

 "Tiger and his family have Nike's full support," read a statement released from the athletic apparel company Monday. "We respect Tiger's request for privacy and our thoughts are with Tiger and his family at this time."
