Why did Heidi Klum chop her long, blonde locks into a layered rocker 'do?

"I got bored," the Project Runway host, 36, explained on The Tonight Show With Jay Leno Tuesday night, "as we all do every once in a while as girls, so I chopped it off!"

Klum says she loves to change up her style.

"I grow it, I cut it," she said. "Some people never change their hair and it works for them. For me, I get bored."

Her husband, Seal, picked up on the new look. "Of course he notices. It would be terrible if he didn't," she told Leno.

The mother of four (Leni, 5; Henry, 4; and Johan, 3; and Lou, 6 months) also opened up about her diet: "No carbs, a lot of vegetables and salad."
