US celebrity chef and TV host Anthony Bourdain has died in an apparent suicide in a French hotel room, says CNN.
The US network – which hosts Bourdain's Parts Unknown programme – tweeted that the "chef, storyteller and Emmy-winning host" had killed himself.
Bourdain, 61, was found unresponsive in his hotel room in the French city of Strasbourg, where he was filming an episode of the show, said CNN.
His friend, the chef Eric Ripert, found him.
A CNN statement said: "It is with extraordinary sadness we can confirm the death of our friend and colleague, Anthony Bourdain.
"His love of great adventure, new friends, fine food and drink and the remarkable stories of the world made him a unique storyteller.
"His talents never ceased to amaze us and we will miss him very much. Our thoughts and prayers are with his daughter and family at this incredibly difficult time."
Bourdain's bestselling book, Kitchen Confidential: Adventures in the Culinary Underbelly, became a bestseller in 2000 and launched his TV career.
His early work on the Travel Channel won Emmy Awards and in 2013 he moved to news broadcaster CNN and began filming Parts Unknown.
The show also picked up awards and featured Bourdain travelling the world to explore food and culture.
He was in a relationship with Italian actress Asia Argento – one of the many women who say they were sexually assaulted by Harvey Weinstein.
One of the first to play tribute to Bourdain was British presenter Nigella Lawson, who worked with him on a US show called The Taste.
