Rising popular girl group f(x) member Amber revealed the story behind her short hair. On the 16th, the singer revealed through MBC variety talk show Radio Star, "Since I was little, I often heard that I look like a boy." Additionally, to the question the MC asked of whether SM Entertainment recommended Amber to cut her hair short, the f(x) member replied, "No. I just cut it short because it's easy to take care of." Furthermore, comedian Shin Jung Hwan who was present at the show cleverly commented, "I thought Dong Hyun came with makeup on," making the studio members laugh. Amber then caused more laughter by impersonating the expression of a llama, an animal she's said to resemble. f(x) released their first album on May 3rd and are busy promoting their newest song Nu ABO.
