The singer submitted his own paperwork to end his seven-year marriage to Heidi Klum today, four days after the supermodel filed for divorce. Seal also cited "irreconcilable differences" as the reason for the breakup, but he asked for joint legal custody of their four kids, while Klum requested primary physical custody.
