The normally confident Tiger Woods turned greener than the links of St. Andrews before popping the question to his Swedish girlfriend, Elin Nordegren.

"I was super nervous the moment I was going to put the question to [her]," he told Swedish newspaper Svenska Dagbladet, which released the story on its Web site yesterday.

Woods, 27, proposed to the former model last month when the pair traveled to the Shamwari Game Reserve in South Africa for a four-day vacation.

The proposal was far from impromptu. Tiger said he had made extensive plans on how to ask the big question, planning the right moment in between his hectic golf schedule.

"I had made up my mind many months before, but I wanted to wait for a perfect and romantic setting," Woods said.

"It was a thriller. To putt for victory in a major [golf tournament] is nothing in comparison. Even if you say 'Will you marry me?' with the right feeling, the answer could be 'No.' "

But Woods didn't bogey his big chance. Nordegren, 23, said, "Yes," to the delight of the world's best golfer.

Woods, however, said earlier he was infuriated when Adrian Gardiner, the owner of the South African resort, broke his promise of privacy by arranging a public send-off and leaking the news of the engagement.

"I was betrayed by Adrian Gardiner," Woods wrote in his newsletter to fans. "He promised to protect my privacy . . . but went back on his word . . . Saying we were uncomfortable and totally shocked is an understatement."

Tiger, who is known for guarding his privacy, was also outraged that details of the couple's deeply personal moments were revealed by the reserve's staff.

"Woods and Nordegren walked away into the bush, where he proposed to her," a reserve spokesman breathlessly informed reporters.

The golfer said that neither he nor his fiancée will ever revisit the resort.

The pair, who met when Nordegren was working as a nanny for Swedish golfer Jesper Parnevik, "haven't set a wedding date or decided where [they'll] get married," Woods told the paper.
