may i know who is yuri's bff in snsd?

I think is yoona..^^

its Jessica!!!... we often see Yoona and YUri together chatting and doing crazy things but her real bff is Sica..

Yuri and Yoona are best friends. Yoona dicho it herself and Yuri dicho that Yoona was there for her when nobody else was.

Yoona! It must be her. Yuri, Yoona and Seo are three best friends I think. They've known each other since they were very young... So easy to understand *grins*

Yoona o Jessica o Tiffany
