Rumor is that her boyfriend in her story in TV show "Golden Fish Tank" that broke her heart was Yoon Gae-Sang, ex-G.O.D member who now is active in dramas and movies. This seems like a very well-known rumor.

Also, there is a rumor that she went out with actor Song Seung-Hun.

One more: a FIN.K.L member (most likely either Sung Yoo-Ri or Lee Hyo-Ri) was rumored having a relationship with singer Eun Ji-Won and rumor is that they broke off because Eun Ji-Won was too crazy with online games.
