Everyone knows Korea is where to go for plastic surgery haha. If she did get it I'm sure that's where she went.
It's the place to go for Asians, it's cheaper and quality is good but I also heard since there are so many people going to Korea for PS these days, there are also a lot of shady/fake/not standard places as well.
The go to Korea thing is just stereotype thing, but not with out reason. Plenty of places, surgeons can get the job done. LOL Just use the same surgeon for Ailee, Jessica from SNSD, basically anyone JYP approved or BRAVE brothers lolz.
