Pop star Seal and supermodel Heidi Klum have decided to split, the two said in statements released by their publicists. "While we have enjoyed seven very loving, loyal and happy years of marriage, after much soul-searching we have decided to separate," the statements said. "We have had the deepest respect for one another throughout our relationship and continue to love each other very much, but we have grown apart." Seal and Klum have four children together -- Leni, Henry, Johan and Lou.
