Cabler Bravo's upcoming fourth season of its reality cooking show Top Chef Masters includes three openly gay chefs.

Premiering on July 25, Top Chef Masters season four takes place in Las Vegas with 12 award-winning chefs competing for the title and a chance to win $100,000 for the charity of their choice.

Celebrity chef Curtis Stone is back as series host alongside returning judges James Oseland and Ruth Reichl. They'll be joined by two new judges this season: Krista Simmons, a food and travel journalist whose work has appeared in the Los Angeles Times and New York Magazine, and Francis Lam, features editor of Gilt Taste.

Openly gay contestants include Art Smith, Mark Gaier and Clark Frasier.

Smith, a two time James Beard Award recipient, is the executive chef and co-owner of five restaurants, including Table Fifty-Two, Art and Soul, LYFE Kitchen, Southern Art and Joanne Tratorria. Smith appeared in the first season of Top Chef Masters.

Gaier and Frasier are the owners of Arrows, which was named as “One of America's 10 Most Romantic Restaurants” by food glossy Bon Appetit.

“Everything here at Arrows is done in house,” Frasier said in a video interview. “We make our own cheeses, we grow our own vegetables, we cure our own prosciuttos, we make our own salamis, we make our own pepperoni, we maker our own bread, we make our own ice cream.”

The chefs met in 1985 while cooking at Jeremiah Tower's Stars Restaurant in San Francisco. They also own MC Perkins Cove and Summer Winter.  All three restaurants are located in Maine.

Gaier is competing for the Equality Maine Foundation, which champions gay rights.
