Tiger Woods had an affair with another woman, the new issue of Us Weekly, on stands Wednesday, is reporting.
Jaimee Grubbs tells the magazine she met Woods in April 2007 when she was 21 years old and working as a cocktail waitress in Las Vegas.
Grubbs says she and Woods had sex more than 20 times over a 31-month affair.
She also says she received more than 300 racy text messages from the pro golfer -- and even a voicemail on Nov. 24 from Woods in which he suggests his wife, Elin Nordegren, may know about their affair.
Reports have surfaced that Woods had an affair with VIP club promoter Rachel Uchitel, which she called "ridiculous" in Tuesday's New York Post.
Woods was injured in a car accident outside his Florida mansion early Friday morning. TMZ.com reported that he and Nordegren had been arguing over his dalliances with other women.
On Monday, Woods bowed out of the Chevron World Challenge in Southern California due to his crash injuries.
He and Nordegren are parents to daughter Sam, 2, and son Charlie, 10 months.
