Heidi Klum, 47, and ex-husband Seal, 57, appear to have entered a legal disagreement about the model traveling with their four children Leni, 16, Henry, 14, Johan, 13 and Lou, 10, to her home country of Germany. The Germany’s Next Topmodel host has alleged that the singer’s “time” with their kids is “sporadic at best” in legal declaration documents obtained by People magazine.
