Speaking about the celebration-to-be, Klum tells Redbook for its June issue (on sale May 25): "We love to renew our vows. It's our time – a lovely family time. It's about remembering this moment of love we gave to each other and reinforcing it."
Then there's the attraction for children Leni, 6, Henry, 4, Johan, 3, and Lou, 7 months. "It's so special to us, something we love and something our children have gotten accustomed to," says the Project Runway host, 36. "It's like, 'Hey, Mom and Dad love each other and they get married every year!' "
Expressing his view of their tradition, Seal, 47, says, "Each year, Heidi and I get remarried. It's a great party, but for about an hour, we go off on our own down to a private beach. We sit there with the kids and read vows to each other as the sun sets. It's a very special moment to us."
Speaking admiringly of her "sexy and handsome" husband, Klum gushes, "I don't know why I got so lucky. I have to pinch myself often and say, 'Is this just a dream?' Not only do I love my husband for the obvious reasons (ahem, his sex appeal), but also he is one of the kindest, most loving men I have ever met.
"He is sexy to me because he is fearless and not afraid to show his emotions. He is a supersexy, hot kisser and … he is sexy to me because he can be singing in front of 25,000 people one minute and, the next, be changing our daughter's diaper."
