Gisele Bundchen is the world's highest paid model -- but how is she as a singer?

The 33-year-old lends her voice to H&M's fall campaign, recording a cover of "All Day and All of the Night" by The Kinks in a new promo video for the retailer.

The song will appear in TV and online commercials starting September 12 and will be available for free on and on iTunes. For every iTunes download, H&M will make a donation to UNICEF.

"I am so excited to be the face of H&M this autumn. I love the street style look, and that we can raise funds for a good cause. I hope everyone downloads my song!” says Gisele.

It's clear Tom Brady's wife is having a good time in the video and we love that it's all for a great cause.

How do you think she sounds though? The commenting is disabled over on H&M's YouTube page -- so sound off below!
