Despite the short stint with a sleek bob back in 2008, Heidi Klum's signature hairstyle typically consists of long, blond layers. But yesterday, the longtime model debuted a much shorter, choppy bob with blunt bangs. Last night on The Tonight Show, Heidi revealed the reason behind the new style. "I got bored as we all do every once in a while as girls," she explained. "Whenever I get bored I change it. I grow it, I cut it. I grow it, I cut it," she quipped. What do you think of Heidi's new look? Are you glad to see her switch it up, or do you prefer her with her tried-and-true go-to style?
