His close friend Eric Ripert, the French chef, found Bourdain unresponsive in his hotel room Friday morning.
Bourdain's death came three days after fashion designer Kate Spade hanged herself in her Park Avenue apartment in NY.
The tragedy of the suicide death of Anthony Bourdain is being complicated by bureaucracy as his body will have to stay in France for at least a few more days. Spade's husband and business partner said the 55-year-old business mogul had suffered from depression and anxiety for many years.
"He is absolutely the last person in the world I would have ever dreamed would do something like this", Gladys Bourdain, who was a longtime editor at The New York Times, said.
The death of Bourdain by apparent suicide moved Wang to donate one day's profits to the suicide prevention hotline.
"He had everything", she added.
In the heartbreaking statement, which Argento shared on Twitter, she wrote: "Anthony gave all of himself in everything that he did. Money beyond his wildest dreams". "He had a choucroute for lunch".

Stelter aired photos of some of the tributes to Bourdain at CNN headquarters in Atlanta and NY.
Cinematographer Zach Zamboni, who worked with Bourdain on his food and travel shows "No Reservations" and "Parts Unknown", has a home in Portland and grew up in Milo.
Since Friday, mourners have gathered to leave flowers and messages at Brasserie Les Halles, the now-shuttered Park Avenue restaurant where Bourdain became the executive chef in 1998 and immortalized the experience in his 2000 bestseller, "Kitchen Confidential".
