Glitter was a mistake that needn't ever be replicated. That's why some fans and foes of Mariah Carey were nervous when they heard she had a meaty role in Lee Daniels' new film, Tennessee. As it turns out, some critics say, she isn't half bad. Daniel's was so impressed with her that the Monster's Ball producer has also cast her in Push, an upcoming film in which she'll play "a Harlem social worker ministering to an obese, HIV-positive woman impregnated twice by her father." Sounds…ambitious. No baby steps for Mariah Carey! [NYDN]
