Korea's leading actress Kim Hye-soo, 40, and actor Yu Hae-jin have been dating for over two years, according to a sports daily.

The paper revealed the apparent lovers along with some paparazzi photos. One of them showed the couple meeting in front of a car, lightly disguised with sunglasses, a swine flu mask and a cap.

According to the newspaper, they date every Friday night, and participate in each other's family gatherings.

It is actually not the first time that rumors regarding a Kim-Yu romance have been reported by media, although the two have continuously denied such rumors.

The two first acted together in the 2001 comedy "Kick the Moon." But since the big-screen drama "Tazza: The High Rollers" (2006), speculation reached a feverish pitch, with one newspaper even predicting their marriage.

Kim and Yu's management agencies this year denied any relationship was taking place last week, saying that "the two are close friends, but not lovers."

Not put off, the media seem to be quite sure about their relationship this time around. Newspapers and magazines have amassed a treasure chest of evidence - pictures, interviews with associates, as well as clues on Kim's personal homepage, which features phrases like "I love you" and "one love."

Kim is currently taking a break after finishing last year's television drama, "Style," and Yu is featured in "Jeon Woo Chi: The Taoist Wizard," which is currently showing at local theaters.
