Heidi Klum Talks Guitar Hero, Whiplash and Rug Burns with Ellen Degeneres

Project Runway host Heidi Klum got playful with Ellen Degeneres on Degeneres' show Monday, tussling the talk show host's hair and chatting about the whiplash and rug burns she got from her hot new Risky Business style Guitar Hero ad.

With action flick director Brett Ratner at the helm of the new Guitar Hero ad, the 35-year-old Victoria’s Secret model strips down to her socks and underwear and spoofs Tom Cruise’s infamous scene playing the guitar in his socks and a business shirt to the tune of Bob Seger’s “Old Time Rock and Roll.”

The German born Klum told Degeneres the rigorous ad shoot went on for five hours and gave her “backlash.”

"The problem is head banging, right. I felt like someone hit me in the car. I had backlash,” Klum said.

Degeneres laughed and corrected Klum, saying she was sure “backlash” is something although she’s not sure what.

But whiplash wasn’t the only injury Klum sustained during the grueling shoot. "The next day I couldn't move anything. Then I had like a rug burn... for the wrong reasons,” Klum joked. “Because I had to jump off the table and land on my knees with the guitar. It literally went for five hours straight, but it was fun."

Klum, who's married to singer Seal, kicked off the interview by fluffing out Degeneres’ hair, telling the talk show host it needed more lift. Degeneres, who married Portia de Rossi this summer, reciprocated by mussing Klum’s blond locks.

Following the mutual hair fluffing a flirty Klum edged close to Degeneres and asked “What are we going to do now?”

“I don’t know yet,” Degeneres teased back before saying, “Well were both married. Nothing.”
