Tiger Woods says he has let his family down and regrets "those transgressions with all of my heart."
In a statement Wednesday on his web site, Woods says he has not been "true to my values and the behavior my family deserves."
He offered his "profound apology" to his supporters.
His comments came after US Weekly magazine published a cover story alleging that a Los Angeles cocktail waitress had a 31-month affair with the world's no. 1 golfer.
