Both chefs reference their ongoing skirmish at the South Beach Wine & Food Festival

Feuding celebrity chefs Anthony Bourdain and Paula Deen went another round Sunday at the South Beach Wine & Food Festival in Florida.

With both chefs on hand for separate cooking demonstrations, Bourdain, 55, wasted no time slamming Deen, 65, yet again for agreeing to endorse a diabetes medication after years of cooking decadent foods.

It began when N.Y.C. chef Eddie Huang asked Bourdain: “Aren’t you a hypocrite – smoking on your show and making fun of this nice old lady with diabetes?”

As the crowd hooted and hollered, Bourdain replied: “You’re right. I did smoke cigarettes for a lot of years on my show. But I wasn’t selling any [expletive] cigarettes And when I found a spot on my [expletive] lung, I didn’t wait three years so I could get a deal selling the patch.”

Meanwhile, at her demo, Deen thanked her fans for sticking by her. “There have been two or three haters. I don’t know why they’re mad at me. I didn’t choose [my diabetes],” she said.

She added: “I don’t care what they say. What I do care about is y’all, and I thank you for the support … I can’t tell you what it means to me.”

The two chefs’ contrasting styles were further accentuated when each was asked for their favorite hangover cure.
