Heidi Klum took her big smile to the cover of InStyle [1] for the magazine's December issue. Posing comes easily to her after all her years of experience, and in the interview she reveals her five rules for success [2], like finding your passion and not taking no for an answer. With Heidi it's never all serious talk, and she also opened up about Seal, singing, and style. Here are highlights:

• On her husband: "Sometimes I lie in bed and I'm like, 'Oh my god, there's Seal lying next to me. What's he doing there?' I get a smile on my face immediately. Our honeymoon period is definitely not over. [We] have date nights. We go to dinner or to the movies. We like to keep it romantic. Some people wake up in the morning and turn over when they see their mate. That's not us."
• On how Seal has influenced her wardrobe: "I've gotten more stylish since I've been with my husband. I was always making fun of him because he has so many leather coats, jackets and shoes. But he looks hot. I want to look good for him. So I kind of stepped it up a bit."
• On her singing voice: "We sing all the time. He's always rolling his eyeballs because I'm in the wrong key. But I know he's laughing about it too. So I'm not a singer — who cares? Not everyone is Seal!"

Not everyone is Heidi Klum either, and the supermodel definitely deserves to credit herself for all her success.
