No, there aren't any pictures of SNSD / Girls' Generation's Tiffany coming out of a car going "commando" however this fancam video of SNSD before the 'Etude' performance Music Core has got netizens going crazy and it has quickly become the number one most searched topic on daum.

Yoona's actions are certainly causing a lot ruckus and a lot of harsh words from crazy netizens.
