January 24, 2007 - Jung Jang Mi is U-Know Yunho's sister?

I had read some rumors about DBSK's U-Know Yunho's sister debuting. Since in G-Star, the only member with surname Jung is Jung Jang Mi, netizens has speculated that she is the sister of Yunho. SM haven't released much information regarding them, so we just have to wait for it.

What do you think? Do they look like siblings?

But why oh why? I think she looks more like Hero Jaejoong's sister..

Or maybe she's YunJae's daughter.....right.
