When f(x) first debuted, they received a lot of attention for three different reasons. One, they are a talented bunch. Two, Amber's tomboy-ish looks surprisingly allured many fans. And lastly, Krystal is the younger sister of SNSD's Jessica. We've seen great sisterly love and support between these two and now we get to see Krystal show her love for her sister by singing SNSD's 'Gee.' On the 5th, f(x) appeared on Maybee's Volume Up radio show and gave us a taste of what 'Gee' would've sounded like if they had sung it. And by the looks of their 'Chu~?' outfits, it looks like they just came from their performance on Music Bank. Check it out yourselves! I have to admit, they sound cuter than SNSD does and I'm really digging it! Now, only if they did some more SNSD covers� Thanks to euphoriaX1993 for the tip! Don't forget to visit Aff(x)tion!
