GUITAR HERO'S UNDERWEAR

A NEW "GUITAR HERO" AD FEATURES FOUR *HUGE* SPORTS STARS . . . IN THEIR UNDERWEAR:

"Guitar Hero" has created another ad inspired by TOM CRUISE'S underwear-dancing scene in "Risky Business". (--They did one of these ads earlier this year on "American Idol" . . . with DAVID COOK and DAVID ARCHULETA.) --This time, they've landed four HUGE athletes to star in it: KOBE BRYANT, ALEX RODRIGUEZ, MICHAEL PHELPS, and (skateboarder) TONY HAWK.
