A mundane ending to one of the most captivating celebrity romances. Supermodel Heidi Klum said through her publicist yesterday that she had filed for divorce from singer Seal after seven years of marriage. The two had been separated since January. The couple, who have four children together, said in a joint statement in January that they had decided to separate after a period of “soul-searching” and that they “had the deepest respect for one another … but we have grown apart.” Over the course of their marriage, the couple held annual vow-renewal ceremonies.
