Mariah Carey and the rest of the Precious female stars were decked out in Cannes Film Festival finery at the premiere of their film.

Mimi opted for a low-key, fitted black gown that showed off her famous physique. After having to keep her ta-tas under wraps while filming the picture, Mariah is now able to set them free, but kept it tasteful for this particular event. Hats off to you, girl, for showing restraint.

But the real star of the film is Gabourey Sibide, who plays the title role of pregnant teen Precious in the film. Sibide, like Mariah, opted for an all-black ensemble still rocking the blunt bangs I love so much.

Paula Patton, however, brought a splash of color to the red carpet with a red, floor-length gown. All in all, I’m just still pretty shocked that Mariah might actually be graduating into grown-up film roles.
