The speculation sparked off after Klum, who split from Seal earlier this year, was photographed intimate with her bodyguard, following which her estranged husband's statement cast doubts on her fidelity.
But the 'Project Runway' host has said in an interview that she remained faithful during their seven years of marriage, reported Aceshowbiz. "When we were together, I never looked at another man," Klum said.
She was also not surprised of Seal's statement in which he said she didn't wait to "fornicate with the help", who in this case is referring to her bodyguard Martin Kristen. "It was a unique choice of word... I'm used to it.
Other people aren't," Klum said. Seal himself has corrected his statement last week. "Seal would like to clarify that he was not implying his wife was cheating while they were together, but he was merely pointing out that their separation and divorce were not final and they are still legally married," his representative said.
