Tiger Woods acknowledged “living a lie,” saying he alone was responsible for the sex scandal that caused his shocking downfall from global sporting icon to late-night TV punchline.

“It was all me. I’m the one who did it. I’m the one who acted the way I acted. No one knew what was going on when it was going on,” Woods told the Golf Channel in one of two interviews Sunday night.

A second one was aired on ESPN, which will also televise the first two rounds of the Masters. Woods plans to end four months of seclusion and return to golf at the tournament next month.

“I’m sure if more people would have known in my inner circle, they would have stopped it or tried to put a stop to it. But I kept it all to myself,” he told the Golf Channel.

Later in the same interview, Woods refers to his serial adultery by saying, “I tried to stop and I couldn’t stop. And it was just, it was horrific.”

Woods answered questions on camera for the first time since his early morning car crash last November, yet again divulged few details about the crash, his marriage, his stint in a rehabilitation clinic or his personal life. Woods insisted those matters would remain private, just as he had in a statement on his Web site right after his crash and again Feb. 19 when he apologized on camera in front of a hand-picked audience but took no questions.

“A lot of ugly things have happened. … I’ve done some pretty bad things in my life,” he told ESPN.
