Who Is The Sexy Girl In Psy's New Song Gentlaman?

   For those who do not know who the girl is:
Her name is Ga-in and she is part of a girl group called "Brown Eyed Girls" or "BEG". They are considered "adult idols" as they are in their mid 20's to early 30's and known for more "adult" material in their songs/MVs (for kpop standards). Their most famous songs are "Sixth Sense" and "Abracadabra". For a softer song try "Cleansing Cream".
