Signed, sealed and delivered -- by Seal.

On Tuesday, Seal filed his own divorce papers to end his seven-year marriage to Heidi Klum -- four days after the supermodel, 38, submitted her own paperwork.

Us Weekly obtained documents confirming that the "Kiss from a Rose" singer, 49, like Klum, cites "irreconcilable differences" as the reason for the split. But Seal has requested joint legal custody of their four kids Leni, 7, Henry, 6, Johan, 5, and Lou, 2. Project Runway host Klum had requested joint legal custody of the tots.

After the couple shockingly announced their separation in January, Seal spoke frequently about the breakup while promoting his album Soul 2.

"Just because you decide to separate, I don't think you all of the sudden stop loving each other," he said in a Jan. 23 TV interview. "I don't think you all of the sudden stop becoming friends."

 "I don't want to talk positively or negatively about the ups and downs that we had," Klum told ELLE mag. "Every couple goes through things. Unfortunately, we're in the public, so the highs are out there."
