Brown Eyed Girls' Ga In is known for a lot of things -- her rich voice, the 'Adam Couple', and many others -- but perhaps her most unique distinguishing trait is her dark eyeliner that she never goes without.

"Eyeliner is my life partner," she said during an interview on MBC's 'Section TV'. "I think we got close during promotions for 'Abracadabra'."

Not only did eyeliner change her life, it also changed her views on her face, she claimed. "I began to think that I didn't need eye surgery anymore."

"It feels really nice to be the hope for single-eyelid women everywhere," she joked.
