Legendary singer Seo Taiji (41) and actress Lee Eun Sung (25) have announced that they will be tying the knot!

Seo Taiji shared the sudden news on his official homepage on the 15th, which came as a surprise to many due to the fact that their relationship was kept under wraps for years.

The two stars first met on the set of Seo Taiji's "Bermuda Triangle" music video in 2008. They developed feelings for each other and began dating the next year in 2009. They've been together ever since and will now take their relationship to the next level.

Seo Taiji and Lee Eun Sung will begin their life as a newlywed couple in their home in Pyeongchangdong, Seoul.

Congrats to the soon-to-be married couple!
