As the cast of the 'Real Housewives of New York City' busies themselves with shooting the next season of the reality hit, Bravo insiders wonder if the show will still be ratings gold without its breakout star, Bethenny Frankel.

"Bethenny is the biggest star the franchise has ever produced," a Bravo insider tells me. "She not only connected with the most fans, but she also allowed the audience to laugh at how ridiculous the other ladies are. Without Bethenny making fun of the cast, the show just won't be as much fun."
