Heidi Klum may be coming under fire for her Halloween costume as Kali, and her once-successful TV show may be on the skids, but she's got at least one more project about to make its debut: Dancing and playing air guitar in her underwear for the new Guitar Hero. She imitates Tom Cruise in Risky Business and plays Old Time Rock and Roll by Bob Segar. We guess it's been long enough since a fashion figure joined forces with a video game - you might remember that Karl posed as a DJ in Grand Theft Auto 3. The next logical step would be someone posing for Nintendo, who's been trying to break into the fashion demographic for a while. Gemma as Princess Toadstool in a new Super Mario Brothers? Makes sense to us..
