Whoa! Model Gisele Bundchen has covered Blondie‘s classic song ‘Heart of Glass’. The song was produced by Bob Sinclar who will donate all the proceeds to Unicef’s education work. This may be the redeeming good coming out of this track, whilst Gisele’s singing is passable her gyrating was unimaginative and irritating. You’re a great model Gisele, please just keep it at that!
