Heidi Klum, Seal Divorce: What Drove Them Apart

The word is that Seal and Heidi Klum are officially separating, leading many to scratch their heads at what drove the notoriously affectionate couple apart. At least one outlet claims to have the answer. TMZ reports that Heidi, 38, split from her singer husband, 48, because of his serious anger issues -- and because of how it negatively affected their four children, Leni, Henry, Johan and Lou.

The source also claims that the divorce was "a long time coming" and that career-driven distance widened the wedge between them -- not any instances of infidelity.

The couple, who have dated since 2003, have maintained busy schedules throughout their relationship. Seal is at work promoting his new album, "Soul 2," which drops in the U.S. on Tuesday, while Klum is due to travel to Germany soon to work on her native country's seventh season of "Next Top Model," which premieres February 23rd.

The supermodel and "Project Runway" host confirmed her decision to separate from the Grammy Award winner Sunday night, saying in a statement: "While we have enjoyed seven very loving, loyal and happy years of marriage, after much soul-searching we have decided to separate. We have had the deepest respect for one another throughout our relationship and continue to love each other very much, but we have grown apart."
