Los Angeles (US), Apr. 15  : Golfing great Tiger Woods is losing the battle to save his marriage and his wife Elin Nordegren may file for divorce soon, according to friends.

According to The Telegraph, Nordegren said to be furious over a television advertisement that Woods filmed for Nike, which featured the voice of his late father. She was also said to have thought her husband would take more time off before returning to the course.

Woods took an indefinite break from golf after details of his infidelities became public last year.

He returned in the Masters at Augusta, Georgia last week, where he finished fourth, but his wife did not attend the tournament.

At the weekend she was seen boarding a private jet alone after leaving their estate near Orlando, Florida.

The television advertisement said to have angered her was broadcast on the eve of the tournament and featured Woods looking directly into the camera without speaking.

A 2004 recording of his late father Earl saying "Did you learn anything?", was played over the footage.

"Elin was violently angry over this commercial and thought it was a cheesy thing to do," a source told People magazine.

Woods, 34, has committed to working at his marriage and so far talk of divorce is limited to friends.

No legal papers have been filed and Nordegren has not instructed a lawyer, as yet.

But one friend told People: "She''s so far beyond hurt now. If she were angry or if she hated him, they might still have a chance to work it out. But she''s beyond that. She''s numb. She just doesn''t care anymore."

Nordegren, 30, a former swimwear model from Sweden, bought a property in her homeland last year. It is currently being renovated leading to further speculation that she may move out.

Experts say if she decides to divorce Woods the settlement could be one of the largest in celebrity history, dwarfing the 150 million dollars paid by Michael Jordan, the basketball star, to his former wife Juanita.

An original pre-nuptial agreement is believed to have given Nordegren the right to 20 million dollarsafter 10 years of marriage. In the wake of the scandal, she could receive 300 million dollars through a renegotiated divorce settlement. (ANI)
