heidi klumHeidi Klum has said it’s tough being a rock hero.

The supermodel recently filmed a TV commercial for video game Guitar Hero, spoofing Tom Cruise’s infamous scene in Risky Business and rocking out to Bob Seger’s ‘Old Time Rock and Roll’.

She explained she strained her neck because “I head banged for five hours straight. There was [also] a lot of jumping and running around.

“And I jumped off the table onto my knees and took a layer of skin off.”
