could someone help me look for this female k-pop singer?

[Minimum_Payne]

I posted the same msg at the j-fan board and if you're wondering, yes this is the same guy.

ok, i'm not a big fan of k-pop so i don't know who's who but recently i went to an electronics store in Hong Kong and they played a video of a female kpop singer performing on a musicstation style kind of show. the performance went like this:

1)a few seconds in the beginning of the PV

2) the PV starts off with the singer getting out of a car. She wore glasses, had her hair tied back and wore a business suit

3) in the actual performance, the girl had a hair style that is kinda like Yuri from the j-pop band called "move." check out the pic of yuri as a reference

4) she wore a skirt and had backup singers

lol this description is probably crap but that's the best I can do. could someone help me find this artist? thanx
