On September 16, tvN broadcast a new episode of 'Taxi,' featuring special guest stars, Brown Eyed Girls!

While the four girls casually cruised around in the car, Kim Gu Ra asked Ga In, "Is the dark eyeliner hiding the possibility that you've been having double eyelid surgery little by little?  I feel like your eyes have gotten gradually bigger since your debut days."

Ga In responded, "I didn't do plastic surgery.  Also, so many people are keeping a close watch on my eyes that I couldn't even undergo surgery.  My eyes got bigger after naturally losing my baby fat. 

Honestly, I went to the plastic surgery clinic once because I wanted to get double eyelids.  However my mother had already told the doctor, 'Tell her that it is impossible to do surgery on her eyes.'  Back then, I cried a lot and gave up on double eyelid surgery.  But around that time, the smokey eye make-up started becoming a trend."

And thank goodness for that or we wouldn't have the Ga-In we love and adore today!
