(Newser) – Anthony Bourdain and his wife are splitting up after nine years of marriage, sources confirm to People. Page Six first reported that the celebrity chef, 60, and 38-year-old Ottavia Busia, a mixed-martial-arts fighter, have "been separated for a while." They have a 9-year-old daughter, Ariane. But Busia tells Page Six, "Because of professional decisions we both have made, my husband and I have been for years in an unconventional relationship. Nothing has changed. We love each other. We respect the decisions the other has made. And we’ll always consider ourselves a family."
