So im ing confused right now ... All my life Ive been thinking that Jessica and Tiffany from SNSD (of course) are half koreans and half americans ... but there are some other guys told me that they are not half american they are pure koreans that they were just born overseas... 

So is it TRUE ??? ... Is it true that Tiffany and Jessica were not half korean half american ???  

Can somebody answer me cause i'm freaking confused ... Google sais that they are american singers but ... I DON'T REALLY KNOW !!!
