(AP) - Tiger Woods is apologizing to his supporters, saying he hasn't been true to his values or the behavior his family deserves.
In a statement on his Web site, Woods says: "I have let my family down and I regret those transgressions with all of my heart."
He doesn't say what those transgressions are. He also asks for privacy, saying "Personal sins should not require press releases and problems within a family shouldn't have to mean public confessions."
Woods' statement comes as Us Weekly magazine published a cover story alleging that he had a 31-month affair with a Los Angeles cocktail waitress.
Jaimee Grubbs told the magazine she met Woods at a Las Vegas nightclub in 2007, two months before Woods' wife, Elin Nordegren, gave birth to their first child. Grubbs claims to have proof of the affair in 300 text messages.
The magazine published what it said was a voicemail provided by Grubbs, asking her to remove her name from caller ID. Grubbs said the message was left by Woods three days before his Friday morning car crash outside his Florida home.
