Gunther Klum isn't happy to say auf wiedersehen to his son-in-law Seal.
Hours after Heidi Klum and Seal announced their separation after seven years of marriage together, Us Weekly spoke with Gunther Klum, father to the supermodel and Project Runway hostess, 38.
"We are very sad," German cosmetics executive Gunther told Us via phone early Monday. He added that he needed to touch base with his newly single daughter about the shocking news.
Heidi and the "Kiss from a Rose" singer, 48, share three biological children -- Henry, 6, Johan, 5, and Lou, 2, plus Klum's 7-year-old daughter from a previous relationship, Leni, whom Seal adopted in 2009.
"While we have enjoyed seven very loving, loyal and happy years of marriage, after much soul-searching we have decided to separate. 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," they said in their statement, adding that the split will be an "amicable" process.
"They've had a very rough road lately," a pal told Us. "They're either madly in love or having crazy fights."
