Seal is a highly successful singer and songwriter and is also an ex-husband of supermodel Heidi Klum. Seal is highly recognizable due to scars on his face and for his teeth. His teeth are of misshapen shape and are everywhere. More noticeable is the gap between his upper front two teeth. But we can’t complain as he has dated two big and beautiful supermodels in Erica Packer and Heidi Klum.
