WENN 1 / 6

Somewhere, Kim Zolciak's wig-maker and Botox supplier are anxiously wringing their hands, worried that the gravy train might be coming to an end. Word is, the double-D-cupped, "Tardy to the Party"-caterwauling "Real Housewives of Atlanta" star and her always-blunt on-camera rival, NeNe Leakes, could be handed their walking papers by the powers that be at Bravo.

The New York Daily News claims that producers are "fed up" with the "diva-esque requests" from the frenemies, who are supposedly asking for a bigger chunk of change for the show's third season.

"Bravo has been taking meetings with some notable and wealthy Atlanta women about possibly joining the show," says the snitch. "They're trying their best to keep the process under wraps, but they're gearing up to make a major move in the third season."

According to the spy, the new addition would either replace Kim and NeNe or, if the oddly dynamic duo (hey, don't judge our small-screen addictions) can hammer out a deal, join them, along with fellow housewives Kandi Burruss, Lisa Wu-Hartwell and Sheree Whitfield.

One name that was floated (and immediately weighed down with cement shoes): stylist Tameka Foster Raymond, whose divorce from Usher was finalized in November, nine months after she nearly died during a liposuction procedure in Brazil.

"Tameka isn't very popular in Atlanta," explains the insider. "The producers asked each one of the women how they would feel if she were cast, and they all said that they'd walk. That's the one thing they've been united about."

For now, Bravo is staying tight-lipped on the fate of the cast, although Kim doesn't seem at all concerned.

On Wednesday, she tweeted, "Have I mentioned how happy I am!"
