Anthony Bourdain is not known to hold his tongue back when it comes to Food Network hosts. He's thrown jabs at Bobby Flay, Giada De Laurentiis but the "Parts Unknown" host's particular favorite is Guy Fieri.

"I tell jokes about Guy Fieri," Bourdain told People magazine. Last summer, he mocked Fieri for "being 52 years old and still rolling around in the flame outfit."

According to E! News, the "Diners, Drive Ins and Dives" host/chef isn't backing down. In a recent interview with GQ, he said Bourdain has "definitely gotta have issues, 'cos the average person doesn't behave that way." He goes on to say, "It's actually disappointing...I don't like him making fun of people, and I don't like him talking s--t. And he's never talked s--t to my face."
