The German supermodel - who is currently expecting her fourth child - feels lucky to have met the British singer and knew immediately he was the one for her.
She said: "We had a very strong connection from the start - it was love at first sight. He's a very gentle giant of a man, a true gentleman, a strong person and a good man. He has a wonderful way of looking at the world. I appreciate that and saw it in him from the beginning."
Heidi says one of the main reasons their marriage works is because they can be comfortable and honest with each other.
She said: "One of the things I love the most is that we can be spontaneous. He spends hours playing with our children and explaining things. It's beautiful to see that in a man. I was looking for someone you can be yourself with, have fun with and not worry about putting on an act with.
"He walks into a room and radiates this wonderful spirit and overwhelming presence."
