Heidi Klum and Seal, who were so in love that they renewed their vows every year to commemorate their wedding anniversary, shocked everyone when they announced in January that they had split after seven years as (serenading) husband and (supermodel) wife. Not surprisingly, the tone between the parents of four quickly switched from lovey-dovey to hostile, and after Klum began dating her bodyguard Martin Kirsten in the summer, Seal made a comment to TMZ cameras that she was "fornicating with the help." Seal has since apologized.
