Heidi Klum describes Seal and herself as 'yin and yang' Heidi Klum and Seal are splitting up because -- why? Can someone remind us please, as the couple-in-love stuff just keeps on coming. "I don't know why we work, my husband and I. We just do," the "Project Runway" host told InStyle UK, which she covers in March. We are black and white -- yin and yang. To me, his beautiful face, great body, amazing heart, voice, his ability to be a loving, caring person and father ... what can I say? Well, that was what she could say before they split up, we presume, given magazines' long lead time. Model Klum and singer Seal, parents of four, announced Jan. 23 that they were separating. "I'm determined to mark our wedding every year with a really great party," Klum told the mag (via the New York Post). We all work very hard and time goes by so fast and you can stumble over years without symbolic peaks in your life to remember -- so we create those. The two have renewed their vows annually since their May 2005 wedding. Last week Seal told Ellen DeGeneres how much he and Heidi love and respect each other, even though they're breaking up. Speaking in the present, however, Klum broke her post-split silence Tuesday. "Hi everyone, I want to thank u for all your support & kind words," she said on Twitter. Really means so much. Thanks again...to the best fans in the world! xoHeidi. One tidbit revealed by InStyle, having nothing to do with her relationship? Supermodel Klum says she's more about jewelry than clothes, and that the jewelry doesn't always have to be right on trend. Check out her cover-shoot video below.
