I'm not so sure also if Niko was doing her a favor or if it was the other way around. But, anyway I think her time would have been better spent on an event like the video below. It was from "Foot Concert" held just last week.

I would have loved to see her on the stage with my other favorite French singers Jenifer and Claire Keim!
