Bieber Fever shows no signs of slowing down, and neither does his marketing savvy. Soon Justin Bieber's adoring fans will be able to bring the Proactiv spokesman's charm to their fingernails. Nicole by OPI is teaming with the teen heartthrob to create the One Less Lonely Girl nail polish collection, which launches at Walmart in December. The shades allude to JB's tunes (One Less Lonely Girl Glitter, for instance) and are likely to cause all sorts of tween swooning in the beauty aisle. It's an odd collaboration from a guy who doesn't wear nail polish himself, but we have a hunch that putting the Bieb's name on almost anything means instant sell-through.
