My heart breaks for Tony Bourdain. May he rest in peace now. He was a friend, a collaborator, and family. A huge personality, a giant talent, a unique voice, and deeply, deeply human. My heart goes out to his daughter and family, and his longtime partners and friends at ZPZ.

According to AFSP, there are nearly 45,000 suicides every year in the US. Shocking. I was saddened to hear of the deaths of Kate Spade and Anthony Bourdain. RIP. It illustrates that success is not immune to depression. We all need to be more aware of our friends who are suffering

Bourdain's death comes three days after American designer Kate Spade, who built a fashion empire on her signature handbags, was found dead in her New York apartment of suicide on Tuesday.

Bourdain's profile began to soar in 1999, when the New Yorker magazine published his article "Don't Eat Before Reading This," which he developed into the 2000 book, "Kitchen Confidential: Adventures in the Culinary Underbelly."

He went on to host television programs, first on the Food Network and the Travel Channel, before joining CNN in 2013.

The celebrity chef had praised Filipino food, calling it the "next big thing" and expressed a fondness for lechon, and sisig.
