Norman, 55, wed Australian interior decorator Kirsten Kutner, 41, before a small group of family and friends. His son Gregory, Jr. was best man.
Speaking to Australia's New Idea magazine, Norman said that everyone was barefoot and dressed in white for the private nuptials.
"Kirsten walked down the aisle on her own – we were all waiting for her," Norman said. "To me, she is the most beautiful woman in the world. She looked stunning."
Kutner was raised in Sydney, but has moved to Jupiter Island, Fla., with her two children Kaya, 6, and Kelly, 3, who served as flower girls. The bride described the wedding as small but memorable.
"We wanted something very intimate with just us and the family," she told the magazine. "It was very relaxed – a beautiful family reunion."
Norman was divorced in 2006 from wife Laura Andrassy after 25 years of marriage. Two years later, in a $2 million Bahamian beachfront ceremony, the golfing great married Evert. The union lasted only 18 months.
Norman and Kutner, who is divorced from a Switzerland-based finance executive, have been friends for many years. They recently reunited last year while Norman was overseas developing a golf course.
"Kirsten is very much in love with Greg and was quite excited about having such a romantic and beautiful island wedding with their families and closest friends," a source tells PEOPLE.
