Heidi Klum shows her wild side, dancing around in her underwear and performing the dance moves of Joel Goodsen, a character made famous by Tom Cruise in the 1983 movie "Risky Business", for the latest commercial of computer game "Guitar Hero: World Tour." In the more-than-30-second ad, which can be watched after the jump, she is seen donning black underwear and playing a guitar to Bob Seger's classic track, "Old Time Rock & Roll."

At the beginning of the ad, Klum is seen wearing a white shirt and a pair of white socks. She moves her head back and forth to the music with both of her hands busy rocking her guitar. Then she sheds off her clothes and starts moving around in what looks like a living room, stepping her feet on the table and throwing herself into to the sofa, still busting out her best rock star moves.

The ad is directed by Brett Ratner, who most recently directed the music videos for Miley Cyrus' hit single "7 Things" and Mariah Carey's "Touch My Body." "He (Ratner) really wanted to have it exactly like Tom Cruise did this ... It was harder than I thought it was gonna be," Klum says on doing the "Guitar Hero: World Tour" ad with Ratner that left her with bruises and burns all over her legs.

Klum is one of the many other superstars who've been booked to film ad for "Guitar Hero: World Tour", which is due for release in New Zealand later this year.
