EXCLUSIVE PHOTOS - Heidi Klum And Seal Reunite For Leni's Birthday

They may be in the early stages of finalizing their divorce, but Heidi Klum and Seal are still fully committed to their four kids!

The former couple reunited Leni's 8th birthday party at a lavish mansion in the Hollywood Hills, on Saturday afternoon, and she definitely got the A-list treatment -- the party had professional caterers!

Despite the fact that the little girl isn't his biological daughter, the musician began dating Klum when she was preg, and formally adopted Leni as his own after her birth. Little Leni, who's full name is Helene Boshoven "Leni" Klum Samuel, doesn't have any contact with her real father, director of the Italian Renault Formula One team, Flavio Briatore.

The German-born model filed for divorce on April 6, and the ex-pair have been hammering out a custody agreement which allows the 49-year-old singer joint legal custody of the Leni, 7, Henry, 6, Johan, 5 and two-year-old Lou, while Klum will have primary physical custody of the kids.

Despite the spilt, they're still keeping the peace!
