This is the demo by the songwriters, a Norweigan band Called Ask Embla. Personally, I prefer the original.
This video looks like it is fun, but Nicole Scherzinger has yet to learn a thing or two about over achieving. Her (And Ciara) always look like they are over doing it, whereas a real diva would probably put just as much effort into her work without showing it. You don’t gotta show that you are bump and grinding in order to bump and grind, if you know what we mean.
