Girls' Generation's Sunny definitely knows how to portray a bad girl image.

Sunny posted a photo of her showing some fierceness on her Instagram account saying, "Bad bad bad bad girl~ #suddenly #badgirl" and gave a treat to her fans by showing a parody of Lee Hyori's "Bad Girl" on her own version.

SONEs who saw Sunny's photo commented, "I love your eyes," "Sexy and cute," and "You look like a rock star."

However, Sunny got her agenda even on Chuseok day. She tweeted, "Have a bountiful Chuseok... Sob, I want to have a Chuseok holiday too." Sunny was spotted leaving for Japan last 18th to push for their Girls' Generation's new Japanese single entitled "Galaxy Supernova".

Sunny is definitely having some hectic schedule. Too bad she wasn't able to celebrate Chuseok as tradition.
