No, but she's in a lesbian love triangle. Here's an excerpt:
"it was a love triangle between Yuri, Han Ye Seul and Son Ye Jin. Both Han Ye Seul and Son Ye Jin are both obsessed with Yuri, however Yuri chose Son Ye Jin because Son Ye Jin has more connections in the acting business and she bought Yuri a car. Yuri never refused any of their advances and used to spend cozy evenings with Han Ye Seul in Han Ye Seul's house. Apparently, both actresses were taking different approaches but Son Ye Jin won at the end and Yuri was heard mentioning her at various occasions and then Son Ye Jin started telling fellow actors that she was crazy over Yuri. This drove Han Ye Seul to depression and she ran away to LA because it became a public affair. Apparently this was published in Sportsseoul.com."
The articles that they publish are usually really crazy but really reliable. One time, they published a rumor and no one believed it, but it was later turned out to be true. I, honestly, believe this. You may believe it or not, whatever floats your boat.
I'M SO HAPPY TO BE A WOMAN
PLUS, this rumor isn't well known at all. I guess SMent tried to keep it a secret? Adds to the reality of it.
