SM Entertainment’s recently announced girl group, f(x) consists of members Sulli, Luna, Krystal, Victoria and Amber. The story behind the f(x) name is kind of nerdy — it’s a mathematical function. The ‘x’ variable in the function represents the girls’ variety of charms and talents. Also, ‘f’ stands for flower and x stands for the XX chromosomes in females.

The faces of f(x) look great but I hope I won’t be seeing those pom-pom looking accessories when they debut. With competitors like Kara, Brown Eyed Girls and 2NE1 in the market, I hope they really got what it takes in terms of fashion, singing and dancing!
