Heidi Klum has denied Seal's recent claims that she cheated on him with her bodyguard Martin Kristen while the soon-to-be-divorced couple was married.

"It is sad that Seal has to resort to this kind of behavior and spread these untruths about the mother of his children," Klum's representative told Us Weekly on the Project Runway host's behalf on Saturday.

Klum, 39, and Seal, 49, separated in January after seven years of marriage and are the parents of four children Leni, 8, Henry, 6, Johan, 5, and Lou, 2.

While Seal originally said he wanted the split to "remain civil" and reconciliation was a possibility, Klum formally filed for divorce in April.

Seal reportedly made his allegations during an impromptu airport interview with paparazzi on Friday when he was asked to comment on recent photos which showed Klum embracing Kristen, her bodyguard of four years.

"Look boys, that's what happens when two people separate. They move on and that generally means [they have] other people in their lives," Seal told TMZ, according to Us. "I necessarily don't expect to Heidi to all of a sudden become a nun, but as always, my main priority is the emotional well being 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... I guess I didn't expect any better from him, I would have preferred Heidi show a little bit more class and at least wait until we separated first before deciding to fornicate with the help, as it were," he reportedly continued to TMZ.

"But I guess you now all have the answer that you've been looking for for the past seven months."
