Mariah Carey gets two new nail polish lines

Mariah Carey is adding to her beauty resume by launching new nail polish collections.

The Hero hitmaker is teaming up with OPI bosses to release the first eight-color range in January (13), with plans for a second line to hit nail salons and retailers later in the year.

Mariah Carey is the first celebrity to land a double deal with OPI - teen sensation Justin Bieber, rapper Nicki Minaj and reality TV star Kim Kardashian and her family only have one collection each.

The R&B superstar, who enrolled in beauty school before her music career took off, also boasts her own fragrance venture.
