Top actor Lee Byung-hun admitted dating actress Lee Min-jung but denied rumors that they are getting married in November.
The two celebrities said they are in a "serious relationship" in postings on their Web sites Sunday.
"I found someone that I want to be with. Now, she has become the most important person to me. And I want to take this relationship seriously," Lee said on his Web site, referring to fellow actress Lee Min-jung.
The 30-year-old actress also said, "I want to tell all of you that we are dating as lovers."
They earlier denied relationship rumors.
In the posting, the 42-year-old actor apologized to his fans for the belated acknowledgement, saying, "We feel really sorry that we were not able to tell the truth."
The actor said he first met the actress during a gathering many years ago but began dating after a casual meeting early this year.
Still, the actress denied rumors that they are getting married in November.
"It's false information," she said. "The two of us are not preparing for marriage, and there is nothing fixed."
Lee Byung-hun has been at the center of the boom of Korean pop culture in Japan along with Bae Yong-joon.
Lee starred in the Hollywood blockbuster "G.I. Joe" and became the first Asian actor to leave handprints in the forecourt of a Hollywood theater.
The actress rose to stardom with her supporting role in the popular KBS drama "Boys over Flowers" in 2009. She later starred in such films as "White Night," "Cyrano Agency" and "Wonderful Radio," and several TV dramas, including "Midas" and "Big." (Yonhap)
