What can’t or won’t Justin Bieber do?

Bieber rakes in $300K per concert. Bieber is crowned as next host of the revamped Punk’d once MTV resurrects that show. Bieber is set to release his first book, Justin Bieber: First Step 2 Forever: My Story on October 12. Bieber sells lines of bedding, dolls and toys.

Bieber Bieber, Bieber…

And just when you thought Bieber had his hand in everything possible, he has pulled the most brilliant marketing move of all: Justin Bieber is now launching a line of glittery nail polish, yes, you read correctly, nail polish, which will aptly be named, “One Less Lonely Girl,” according to fashion site styleite.com.

Bieber’s collection will be sold exclusively at Walmart during the holidays but will later find a much more broad market at your local Target, Sears and Ulta stores.

Tell me, what screamin’, dreamin’, Bieber-lovin’ teenage girl could refuse the urge to buy every single shade of the polish line, in the hopes of bein’ less lonesome, making Bieber even ultra uber richer than he already is…all before his 18th birthday?
