So what's the truth? Are Lee Jang Woo and Oh Yeon Seo dating? Did they ever date? Have they broken up?

The latest word is that the co-stars of the MBC drama "Oh Ja Ryong Is Coming" are no longer an item. Sports Seoul reported that although they couldn't continue as girlfriend and boyfriend, they remain friends.

But there have been contradictory statements about their relationship since the rumors began. The two actors play a couple in the drama. It takes Lee Jang Woo's character longer to realize he likes Oh's character than it does for her to fall in love with him.

And that may be similar to what happened in real life. She may have been a little more interested than he was. Or a little more eager to commit to a public relationship.

The actors initially sparked rumors when they were seen off set, sharing a meal and snuggling close. The actress, who appeared in "Iris 2," was seen blowing him a kiss. Then Lee Jang Woo talked about how close he and his former Dongguk University classmate had become.

"Our relationship is now so close, we can understand each other just by looking in each other's eyes," said Lee, who previously appeared in the comedy "I Do, I Do." "Because teamwork on set is so important, I tried to get close to her from the beginning."

Whether he was more interested in having an on-set than an off-set relationship, such statements made it seem like they were a couple. When asked about the rumors, Oh Yeon Seo's agency said, "It seems they are currently getting to know each other and have been seeing each other for about a month."

But then Lee Jang Woo's agency refused to confirm their relationship. His inability to confirm the relationship may have been what triggered the breakup.

After that the actress' agency confused things even further by saying, "We are a bit shocked at the breakup report since the two haven't dated. They remain good friends."

That's not what people on the set said. A member of the production crew was surprised by the breakup news. "Because the two of them normally got along well, I would never guess they would break up. When I see Oh Yeon Seo getting past her pain from the breakup and continuing to focus on acting, I realize what a good actress she is."

Ouch! It must indeed be hard to play a couple once you've broken up.

Complicating things even further was the Oh Yeon Seo's pretend husband, Lee Joon of MBLAQ. They played husband and wife on "We Got Married" and the news of Oh dating Lee Jang Woo created a public relations problem. According to the show's representatives it was the first time that a relationship scandal was reported while filming the show. Participants are not allowed to date in real life while appearing, so Oh Yeon Seo and Lee Joon's virtual marriage had to end.

And now Oh Yeon Seo and Lee Jang Woo have broken up. Or have they? Still waiting for confirmation from both sides.
