They’ve been doing everything by the book, and Seal and Heidi Klum's divorce just took another step forward.

The “Kiss from a Rose” singer has now filed his own paperwork with the court, seeking joint custody of their four children- Leni, Henry, Johan, and Lou.

Ever since they announced their split, there have been continuous questions as to whether or not Heidi Klum and Seal would be working things out - but now it seems clear that the two are going their separate ways for good.

She certainly has her hands full as a newly-single mother of four, but Heidi Klum is doing her best to manage her parental duties during the life transition period.

The "Project Runway" beauty, who recently split from now ex-husband Seal, was spotted taking her brood out for a bite to eat in Brentwood, CA on Saturday afternoon (February 4).
