When it comes to divorce, there are two words that many in Pennsylvania might not expect to hear together. They are "amicable" and "rage." But those are the terms that are being used in reporting about the announced split of singer Seal and his supermodel wife, Heidi Klum.

With the level of success that both enjoy, chances are this will not be inexpensive as might be expected with an uncontested divorce. Still, the pair issued a statement in which they insist their breakup is amicable. It reads in part, "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. This is an amicable process and protecting the well-being of our children remains our top priority, especially during this time of transition."

There are reports that Klum came to her decision to divorce because Seal has a violent temper. The online site TMZ says Klum is worried that Seal's lack of control over his rage could be hurting their four children. Klum and the singer have three children together and the fourth was from a previous relationship Klum had with an Italian businessman. Seal adopted the girl, however.

In what might be considered an unusual twist for celebrity marriages, there is no suggestion that infidelity has played a role in the split. Klum and Seal were married in a romantic service in 2005 and have renewed their vows every year since then on their anniversary.

"The Daily Mail" of London says the divorce will likely feature a battle over the assets, estimated as being worth many millions.
