Seal insists Heidi Klum didn't cheat on him.

The 49-year-old singer slammed his estranged wife for "fornicating with the help" over the weekend following the publication of photographs of the supermodel and her bodyguard Martin Kirsten appearing close in Sardinia, Italy, but he insists his comments have been misconstrued.

"Seal would like to clarify that he was not implying his wife was cheating on him while they were together. But rather he was pointing out that they are separated and the divorce is not final so they are legally still married," his representative said.

A spokesperson for Heidi - who raises Leni, eight, Henry, six, Johan, five, and Lou, two, with Seal - also slammed the claims: "It is sad that Seal has to resort to this kind of behavior and spread these untruths about the mother of his children."

Seal - who split from Heidi in January after seven years of marriage - had criticized the 39-year-old beauty for not "showing class" in romancing her bodyguard.
