"It seems my strategy of proposing in a public forum, maximizing social pressure, and shocking her into silence seems to have worked," Kwon told People. "Now I just need to plan the wedding before she comes to her senses."
The 33-year-old management consultant -- who was named one of People's Sexiest Men Alive in 2006 -- met Tan, a 29-year-old mortgage bank product manager, in December 2006, the same month he defeatedOzzy Lusth and Becky Lee to win Survivor: Cook Islands' $1 million prize.
"I gave her the Hidden Immunity Idol as a token of my love," Kwon told People. "And I knew she loved me back when she didn't laugh in my face."
