An entry on an online community forum showing the picture of F(x)'s Amber and her sister is getting attention. It was titled "Amber's sister looks exactly like her." In the picture, Amber is posing with her sister looking mischievous, her fingers making a 'V.' Her sister is wearing a fancy baseball jacket while Amber is looking casual in black with a baseball cap. Amber's androgyny almost makes it seem like they are brothers and sisters rather than sisters. 

Netizens showed wild interest at the unveiling of Amber's sister. They wrote comments such as "the only thing that's different is the hairstyle," and "that's Amber's real sister? Awesome!"
