Although Heidi Klum and Seal renewed their wedding vows less than a year ago in Florida, the celebrity couple is now headed for divorce. Klum, a former Victoria's Secret model, and Seal, a superstar singer, have been married for almost seven years. They have four children, including one from Klum's previous relationship.

According to an unnamed source quoted in the media site TMZ, Klum is fed up with Seal's bad temper. But according to another unnamed sourced quoted in the Chicago Sun-Times, Klum has a "vicious tongue."

Whatever may have been going on in their relationship in private, they do seem committed to behaving civilly in public. In an interview with Tavis Smiley on PBS, Seal said that he and Klum are "just not those kind of people" who have ugly celebrity divorces. Instead, "what one has to do in this situation is to remain civil, to retain one's dignity, to be professional, and to understand that we are not the only people on this planet that are going through this."

Klum and Seal are both very busy. Seal, who has won many awards, including four Grammys, does a lot of touring and is going to Australia soon to be a judge on that country's version of "The Voice." Klum, who was second on the 2011 Forbes list of the world's highest-paid models, is launching a clothing line and is involved in several television projects, including executive-producing and hosting "Project Runway."
