TMZ reports that a reality-show veteran claims she had a 31-month affair with Tiger Woods -- and has a voicemail recording and plenty of text messages to prove it.

Jaimee Grubbs allegedly met Woods in Las Vegas in April 2007 when she was a 21-year-old cocktail waitress. According to TMZ's report, in tomorrow's US Weekly Grubbs says she had 20 sexual encounters with Woods, is in possession of racy texts and has a November 24 voicemail from the golfer suggesting his wife might be on to the alleged hanky-panky.

Up until now, Grubbs' claim to fame was being on VH1's "Tool Academy."

Legit or not, the news is yet another blow to Woods' public image, which has taken a heavy beating since news of his single-car accident broke on Friday afternoon.
