Cult nail polish brand OPI has looked to celebrities for its color inspiration in 2011.

First it was tween heartthrob Justin Bieber who was snagged to design a glitter-tastic Nicole by OPI polish line, and now we hear that nail art-loving pop star Katy Perry has mixed her magic for an exclusive collection with the California-based brand, too.

Known for her funky red carpet manicures and penchant for posting Twitter pics of her dazzling digits, the line is big on the flashy and fun factor.

The nail color collection will include Teenage Dream (a plummy pink sparkle), Not Like the Movies (metallic silver), Last Friday Night (a Crayola blue glitter), and The One That Got Away (a deepest dark berry purple.) Each polish will retail for $9, and will launch at Ulta in January.

Katy is known world-wide for her innovative style and is always surprising us with her wild nail designs. When we learned about Katy's love for lacquers, we couldn't resist the opportunity to work together to create this glamorous collection," says Suzi Weiss-Fischmann, OPI executive vice president and artistic director.

With stormy greige and muted shades being all the rage for fall, we're thinking the glitter-filled selections from both the Bieber and Perry lines are looking to inject some much-needed girliness into an industry that has leaned towards neutrals for several seasons straight.

And for those of you that may be hesitant about the Teenage Dream-like color wheel, you can play with the trend by simply swiping Black Shatter on top of your own favorite mani shade.
