Anthony Bourdain?s ex-wife, Ottavia Busia, paid tribute to him on Instagram late Sunday night. Busia posted a photo of their 11-year-old daughter singing in a rock band at a concert, wearing boots that her father gave her. Busia wrote, ?Our little girl had her concert today. She was amazing. So strong and brave. She wore the boots you bought her. I hope you are having a good trip, wherever you are." Ariane Bourdain is the celebrity chef's only child. Bourdain was found dead in a hotel room in France last week.
