First Justin Bieber and now Katy Perry? Other than being international pop stars, what to do the two have in common? They both have nail polish lines coming out. Katy’s mini-collection from OPI will debut in January at Ulta stores. And like Justin’s One Less Lonely Girl collection, all of Katy’s shades are named after her songs, including Teenage Dream (glittery pink), Not Like the Movies (silver), Last Friday Night (glittery blue), and The One That Got Away (berry).

Also included in the collection is a top coat called Black Shatter, which creates a cracked effect when applied over color.

We all know Katy Perry loves to play with her nail designs, often twittering her lastest Minx coating or fun nail art design, so this makes a little more sense to us than a teenage boy launching a nail polish collection.

What do you think about all these celebrities partnering with companies to have their own nail polish lines? Will you carry them in the salon?
