A Los Angeles cocktail waitress tells the new Us Weekly (on newsstands Wednesday) that she had a steamy 31-month fling with Tiger Woods and has a voicemail recording and text messages to prove it.

Jaimee Grubbs, now 24, tells Us Weekly she began having an affair with Woods, 33, in April 2007.

She tells Us Weekly they went on to have 20 sexual encounters.

I guess we shouldn’t be surprised to hear more stories like this. As with the Rachel Uchitel alleged affair, who know what to believe here. Needless to say this has all become a PR nightmare for Tiger Woods, one of the most bankable sports figures in history.

The difference here is that we have a woman who is claiming she had an affair with Tiger, as opposed to the Uchitel story where others are claiming an affair took place, with Uchitel denying it.
