I think most of you still remember about the bra-incident during 2PM performance at Wonder Girls World Tour, Anaheim 12th of June 2010.
I came across YouTube, and found this video.
Looks like the video owner is the one who threw the bra to Nichkhun.
Watch the video to know the real story.

So, we all now know the truth behind that incident.
And each country sure have different culture.
