Navi had previously talked about boyfriend Jang Dong Min's jealousy over her adoration of artist Zico.  The two had even fought about it!  Well, both Navi and Zico appeared on the March 24 broadcast of 'Happy Together 3,' so of course Jang Dong Min's name came up!  

She said, "How many hours is the recording today?  I want to do it for as long as possible.  Zico and I have the same name.  His and my real name is Ji Ho."  Yoo Jae Suk said, "Jang Dong Min is probably watching.. is this okay?"
