Found the video here and watched it.
ThatsHiphop.com Music - Why Jesus?!?!? Lil Asian Boy In Drag Dancing To Christina Aguilera!
Hes pretty good at what he does ,lol. I think its inappropriate for his age to be watching that sort of stuff.
But todays TV shows a lot of inappropriate stuff on TV,
It looks like he was just playing and immitating what he saw on TV. I can see a young girl doing this practing it in her room maybe while watching it on a dvd player from a movie maybe she found lying around the house?
Kind of weird for a boy,but I remember on that show "What would you do" they had a show about little boys playing with or doing girly things and most considered it harmless and something they would grow out of.
As for this video?My biggest worry would be How did he get that outfit ?

and did he upload the video and make it himself or was influenced by someone else to do this?

Its that outfit that really concerned me!
