Please help me find this video
 

I am searching for this video clip, the video is made to look like in the 90s, but I think it`s current, it's in black and white except some shapes in color. The singer is somewhat looks like Christina Aguilera. At the end of the video they throw powder with color at each other. And they dance like MC hammer. Can any one can tell me what song it is from my vague description?
