The Real Housewives of Atlanta started filming Season 13 earlier this month without their OG star, Nene Leakes, 52, but HollywoodLife has EXCLUSIVELY learned why Nene still hasn’t signed her contract and agreed to return. “She wants to be paid what she feels she deserves and she knows her worth,” a source close to the show said. “But it’s also about receiving support to ensure it’s no longer the work environment where she feels set up and attacked just for good TV.”
