Heidi Klum does Guitar Hero World Tour ad. Klum does what she do best acting like a mad woman with little clothes on like she’s another Guitar Hero. Does she even play guitar? No idea. There’s a guitar hero in everone of us, really?  Even Heidi in her lingerie? I guess looks really sell. I wonder whether it will be more effective to have one of the Aerosmith guys doing their ads or a supermodel..hmmm.
