Gisele Bundchen Sings Blondie's "Heart of Glass" in Sneak Peek Video for H&M Ad

Gisele Bundchen is more than just a pretty face! The Brazilian supermodel is showing off her vocal chops for the second time in an upcoming ad campaign for H&M -- and on Thursday, April 10, she gave fans a sneak peek of her performance, a cover of Blondie's "Heart of Glass."

"Here I am song with @bobsinclarofficial and @hm, soundtrack for the summer," Bundchen, 33, wrote alongside the Instagram video. "Out soon, hope you like it!"

The short clip shows the leggy beauty strutting her stuff in a variety of sexy swimsuits, and palling around with French DJ Bob Sinclar, who produced the track for the ad. (The full version will be available for download in May.)

"I never in a million years thought that I would record a song and work with a producer like Bob," Tom Brady's wife gushed to WWD on April 1.

Bundchen previously covered the Kinks classic "All Day and All of the Night" for H&M. Downloads of the song via iTunes resulted in donations to UNICEF for "the purchase of vaccines for children," the fashion giant said in a statement at the time. Added the model: "I hope everyone downloads my song!"
