In the new issue of Us Weekly, 24 year-old cocktail waitress Jaimee Grubbs shares evidence of her text-ual relationship with married golfer Tiger Woods, 33.

Grubbs says she and Woods dated for a 31-month period and had 20 sexual encounters.

To fill the void between their furtive trysts, the pair took to their phones, swapping text messages of the smutty and flirty variety.  

One exchange from Sept. 27, 2009 reads:

TIGER: I need you

JAIMEE: then get your tight ass over here and visit me! I need u

TIGER: I will wear you out soon

JAIMEE: how soon? I got a new piercing

A couple hours later that same day, Woods vows to Grubbs "quietly and secretively we will always be together ...when was the last time you got laid".

In a text-swap on Oct. 18, Grubbs wonders "why I keep falling more and more for u ;)." Woods' unexpected reply: "because I'm blasian :)."

The lovers even exchanged holiday greetings on Thanksgiving -- the day before Woods smashed his SUV outside his Florida home.
