Joslyn James, one of Tiger Wood's many alleged mistresses, said the golf megastar "is a big fat liar," according to U.S. media report Tuesday.

Joslyn James, whose real name is Veronica Siwik-Daniels, held a press conference Monday immediately after Woods's own press conference at his return to competition at the U.S. Masters in Augusta, Georgia.

"My feelings regarding his press conference was, it’s still a big malarkey, he’s not truthful, he’s not honest, he should be focusing this time right now instead of golf so quickly, on his loved ones." James said.

"I also don’t feel that he says he saw things clearly after his father died and after the birth of his children because after the birth of his first daughter Sam, he was with me 10 days later." James said, adding "I still think he’s a big fat liar… We all deserve an apology, those of us who were hurt throughout all this."

The celebrity lawyer Gloria Allred sat at her side on the day and said her client "is considering returning to her career as an adult film star. "

Woods, a four-time champion, held a news conference on the same day, saying to his fans, "To be out there in front of the people, where I have done some things that are just horrible, and for the fans to really want to see me play golf again ... I mean, that felt great...That really did."

But when answering the media's intense questions, he dodged with rehearsed answers and refused to go into details about the therapy he sought or the state of his marriage.

"I need to be a better man going forward than I was before," Woods said. "And just because I've gone through treatment doesn't mean it stops. I'm trying as hard as I possibly can each and every day to get my life better and better and stronger. And if I win championships along the way, so be it."

Woods surprisingly appeared at Augusta National on Sunday and went out for a practice round in preparation for the Master.
