The lovely vocalist Taeyeon of Girls' Generation surprised fans when she decided to give them the middle finger on stage. Despite her beautiful and friendly nature, it seems she may have gotten carried away during her performance.

Dressed in all black and chic leather, Taeyeon was performing to the song "I'm OK" while at the Albatross Music Festival in Vancouver, Canada. When it was time to sing "No thanks, Baby," Taeyeon lifted up her middle which left fans in awe! Check out the crucial moment down below starting at the 1:45 mark!

However, her bold and shocking performance move didn't anger fans one bit - it left them impressed as you can hear the audience shouting "Oh" and laughing in the video. It seems North America is cool with Taeyeon's rough and chic side. 

What do you think of Taeyeon's bad-ass performance stunt?
