Earlier this week, supermodel Heidi Klum and her husband Seal announced that they had decided to separate and file for divorce after seven years of marriage. Of course, a celebrity divorce is not exactly a new thing (see our earlier Georgia family law blog posts on Ashton Kutcher and Demi Moore, Kobe Bryant and, of course, Kim Kardashian) but many people were shocked by this split.

The reason for this level of surprise was likely due to the many pictures painted by Klum and Seal throughout their marriage of their happy and loving relationship and family life. They held vow renewal ceremonies on each anniversary, and in interviews they repeatedly talked about one another with love and respect.

However, as with all marriages, it seemed that the only ones who knew what was really going on were the people in it. According to an anonymous source, Seal had an unpredictable temper that ultimately motivated Klum's decision to file for divorce. "Seal's inability to control his anger has become too much for Heidi," the source told an entertainment website, "in no small part because it's affecting their children."

It appears, then, that Seal's anger was Klum's 'deal breaker,' says an author quoted in a recent article in the Huffington Post. If so, it likely became impossible for her to look past it to see her husband's good points, ultimately leading the couple to divorce.

Klum and Seal were raising four children together: a daughter from Klum's previous relationship, as well as two boys and a girl born during the marriage.
