CAUSE: Why Heidi and Seal Split?

The rumors are true: Despite some sources insisting Heidi Klum and Seal were not really splitting up, the couple issued a statement last night confirming the news. "While we have enjoyed seven very loving, loyal, and happy years of marriage, after much soul-searching we have decided to separate," reads the statement obtained by E!.

But why? TMZ reports that it all comes down to Seal's temper. "It was a long time in coming," says a source, who adds that Seal can't control his anger and Klum didn't want to deal with it anymore. Another insider tells People that distance also made their relationship more difficult, and a friend tells Us that lately, "They're either madly in love or having crazy fights." Yet another tells New York Daily News that Klum is "super-friendly" and "warm," while "Seal is not." (Klum's father will probably be getting a talking-to: He also spoke to Us, revealing that the family is "very sad" about the split.)
