Anthony Bourdain, a celebrity chef and host of CNN's "Parts Unknown," has died in an apparent suicide, the network announced Friday morning. He was 61.

The network says Bourdain was in France working on an episode of "Parts Unknown." His friend Eric Ripert, who regularly appears on the show, found Bourdain unresponsive in his hotel room, CNN said.

"It is with extraordinary sadness we can confirm the death of our friend and colleague, Anthony Bourdain," the network said in a statement. "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."

In his travels, Bourdain has eaten everything from rotten shark to sheep testicles.

"Is there anything you won't eat?" CBS News' Anthony Mason asked Bourdain in 2016.

"I've eaten a lot of bad food, I've eaten a lot of putrefied food," Bourdain said. "It's when no one cares at all, that's soul-destroying. I mean, maybe I take it too seriously, but I will literally -- a really carelessly made burger by a large cynical large company, the contempt implicit in that transaction can really send me into a spiral of depression that will last for days."

This is a developing story and will be updated.
