So the music video has leaked, and the quality ain't that good, but it's Britney, and who isn't interested what's going on with her?
Personally, the video (linked in case the player doesn't work) is more fun than the actual song. Although she could have gone bigger and made the circus aspect creepier, like with contortionists and fire eaters and other carnival-like side shows. I was at least expecting to see some sort of acrobatics.
And randomly, this makes me wonder, when will Ciara make a comeback? She was a good dancer.
