A representative for Heidi Klum has hit back at the supermodel's estranged husband Seal after he criticized her rumoured romance with her bodyguard.

The German beauty separated from Seal in January after almost seven years of marriage, and filed for divorce in April while the Brit lodged his own paperwork shortly after.

She was photographed getting close to Martin Kristen, her security guard for the last four years, during a family vacation in Italy last month, and Seal apparently accused her of starting a relationship with her minder when he opened up about his personal life on Friday.

He told TMZ.com, "Look, boys, you know that's what happens when two people separate. They move on and that generally means other people in their lives. I certainly don't expect Heidi to all of a sudden become a nun. But as always my main priority is the emotional wellbeing of our children.

"To be quite honest, if there is going to be somebody else in their lives, I'd much rather it was a familiar face. I guess the only thing I would have preferred is that... Whilst I didn't expect any better from him, I would have thought Heidi would have shown a little bit more class... before deciding to fornicate with the help, as it were."

A spokesperson for the blonde beauty has since released a statement on Klum's behalf, telling Us Weekly, "It is sad that Seal has to resort to this kind of behaviour and spread these untruths about the mother of his children."

The couple has four kids - Henry, Johan and Lou, as well as Seal's adopted daughter Leni from Klum's previous relationship.
