He says they only met for coffee. She says they are just friends. Both their entertainment agencies say that the fact that 2 PM's Taecyeon and Girls Generation's Jessica met up recently in Japan does not mean they are dating. And yet the rumors keep on circulating.

In fact, rumors about the singer/actor and singer/actress dating have been circulating since 2010. And that's how long everyone involved has been denying them.

When Taecyeon recently appeared on the MBC talk show "Radio Star," to promote 2PM's comeback with the singles, "Come Back When You Hear This Song" and "A.D.T.O.Y." he tried to explain the photographs taken of them in Japan.

The idol actor, who appeared in "CInderella's Sister" and "Dream High," said that when he heard Jessica was in Japan, he suggested they meet after he finished up at the gym. It was just a casual meet-up between good friends.

"Taecyeon and I are just good friends, nothing more," said Jessica, who appeared in the drama "Wild Romance." "We have a lot in common, such as our American upbringing, but we are not dating. Truthfully, I don't think I could ever date him, because I just can't forget my first love."

Shortly thereafter both agencies made their official statements. But it's not the first time, the agencies had to publicly deny the relationship.

In 2011, after the two were seen eating at a café and she drove him home to his dorm, there were also lots of rumors. Then Taecyeon's agency, JYP Entertainment, released a statement saying that all members of 2PM and SNSD are close to one another. Jessica and Taecyeon specifically have a close friendship, but they are definitely not dating."

Jessica's agency, SM Entertainment, issued a statement saying that "rumors of them dating are groundless."

At that time Jessica attempted to explain why they could not date by offering information about her mysterious first love. She met her first love during her trainee days.

"He seemed rather indifferent, like he didn't think much of me one way or another, but I definitely liked him and made my feelings clear after a short time," said Jessica.

She described her memories as precious and said she would get goosebumps every time her mystery love touched her. But when pressed for his identity, she could only come up with a first name, "Aircon." This sparked a frenzied Internet search among fans with no results. Was the name made up? No one could find out her mystery lover's identity. Two years later no one has.

Taecyeon was recently quoted as saying he would date his "We Got Married: Global Edition" pretend wife, Chinese actress Gui Gui in real life, but she was quoted as saying she did not think it would work out. The poor guy seems to have a hard time getting a date and, if the Jessica rumors are false, then he has been consigned once again to the friend zone.

What do you think? Are Taecyeon and Jessica really dating or just friends? And if they're friends, isn't it about time they started dating?
