With rumors continuing to swirl around a pending engagement announcement, sources close to the pair say that actor Jang Dong-gun and actress Ko So-young will tie the knot at Hotel Shilla in central Seoul on May 2.

As two of Korea's top stars for nearly 20 years, there's also some speculation around the small fortune this pending merger will generate. Jang, who is known as "walking small business", is thought to be worth more than 10 billion won ($8.7 million). Ko herself is worth at least just as much, and according to the newspaper Ilgan Sports, it is estimated the combined sum of their assets is going to reach nearly 30 billion won. With their marriage, their value is only expected to grow.

Jang and Ko, both 37 years old, each debuted in 1992. Acting together in the movie Love Wind, Love Song in 1999, they became and stayed good friends. But about two years ago, during respective breaks from work, they became more than just friends. They finally outed themselves as a couple last November.
