Shakira will only release a song if it makes her hips move, because if she can't dance to it no one else will.
Shakira only releases music that makes her hips sway.
The 'Hips Don't Lie' singer uses an unorthodox method to ensure her latest tracks reach her high pop standards - if they don't make her dance, she scraps them.
Shakira - who is famous for her shapely rear - explained: "I'm not a trained dancer. I did a little bit of gymnastics when I was 12 - everything else it's just me feeling the music. But I do have an unorthodox ways to approve my music or test it.
"When I'm in the studio and I'm producing my own music, I've got to make sure I connect to it at a physical level. My body has to move and my hips have to move and if I don't see that kind of reaction, that physical reaction, then I know that something is not working."
The 32-year old star also spoke about the raunchy video for her latest track 'She-Wolf', admitting she enjoyed writhing around sexily as she is so proud of her body.
She said: "I'm less shy now that I've hit my 30s. After that happens you feel a little bit more free, you accept yourself in many different ways and you're more comfortable in your own flesh." |
