Seal has been preparing to move out of the marital home he shared with Heidi Klum “for weeks,” sources tell us. The couple, who on Sunday night admitted they were separating after six years, have been going through a “rocky period,” sources said. They’re believed to have fought while spending the holidays in Aspen, and Seal has since been looking for a new place. Seal tells PBS’s Tavis Smiley on a show airing Friday that the breakup isn’t ugly. “We’re just not those kind of people.” He added, “What one has to do in this situation is to remain civil, to retain one’s dignity . . . we are not the only people on this planet that are going through this.”
