Calling all nail fanatics: Mariah Carey is about to revamp your manicure! For its latest collaboration, OPI teamed up with the singer/American Idol judge to develop eight Grammy-worthy hues—including the new Liquid Sand polishes, which impart a matte, textured effect. "Mariah is very passionate about beauty and her nails in particular. To pay homage to her iconic status, we wanted to launch her collection with something new and exciting," said OPI executive VP and artistic director Suzi Weiss-Fischmann. "The Liquid Sand nail lacquer offers a never-before-seen look with a pebbled finish that lightly shimmers with fine glitter particles." We can't wait to get our hands (and nails) on a bottle—or vice versa! The Mariah Carey line hits stores in January, but you can preview all the nail polish colors ($9 each) right now.
