Earlier today, Jaimee Grubbs, of VH1's Tool Academy quasi fame, came forward to allege that she had been having a 31 month affair with golf great Tiger Woods. She says that she met the athlete in Las Vegas back in April 2007 and have slept together at least 20 times since. Those of you doing quick math are correct:

In fact, Us promises that tomorrow, it will post a voicemail Woods left Jaimee Grubbs last Tuesday in which he says his wife, Elin, may have caught on to the affair.

Could it be that Jaimee was the mistress whose involvement with Tiger triggered Elin's wrath, and that Rachel Uchitel wasn't even involved (which she claims)?

While Tiger and Elin will not face charges after the incident last week he crashed his car into a hydrant and a neighbor's tree after presumably fleeing his mansion in the midst of a nuclear fight with her he's still got a lot of explaining to do.

That's assuming Grubbs is even telling the truth, of course.

Right now, it's all speculation. But if Us' voicemails and texts are valid the celeb gossip magazine claims Jaimee's given them the goods it could get really ugly.
