Watch world's highest-paid supermodel Gisele Bündchen sing Blondie's Heart of Glass for H&M campaign

33-year-old blonde stars in ad which will raise funds for Unicef

The world’s most famous and highest-paid supermodel makes a real bid for pop stardom.

Giselle Bündchen appears dancing on a Costa Rican beach singing Blondie’s Heart of Glass in a music video for H&M’s summer 2014 campaign. Not only she’s the body and face of the new collection, she is the voice too.

This is not her first attempt to indulge fans with her voice, last year she sang "All Day and All Of The Night" by The Kinks for the Swedish brand’s autumn/winter campaign.

The music video begins with the Brazilian supermodel in a music studio saying: "Are you ready Mr Bob Sinclair?" Followed by the supermodel, posing in the sunshine in H&M's swimwear.

The producers of the track, H&M, Bündchen and DJ Bob Sinclair, will donate all to Unicef, as they did with the first song.

Whether it finds itself at the top of charts or not, it's was an opportunity for the Brazilian model to show off something different than that body in H&M's swimwear and for H&M to help a good cause with a campaign.
