The award-winning chef's tragic death was revealed by Australian television network Network 10 on the same day the latest season of "MasterChef" was due to air. Oliver shared a photo of himself posing with Zonfrillo and "MasterChef Australia" judges Melissa Leong and Andy Allen, saying he was in "total shock." I truly enjoyed the time we spent together on MasterChef in Australia.
