diet coke nail polish

For digits that really pop! Diet Coke and Nails Inc. City Collection nail polish.

Um, when did Diet Coke become all the fashion rage?

First Karl Lagerfeld shot the campaign for Coca-Cola Lite and unveiled his own signature bottle.

Now, the bubbly beverage has inked a deal with Nails Inc. to launch the Diet Coke City Collection, Marketing Week reports.

Inspired by the fashion hotspots of London, New York, Paris and Milan, the bold nail polish line will be given away free (yay!) with every purchase of two 500ml bottles of Diet Coke at Boots (which is in England, so boo!) sold until June 30, according to the source.

The four-piece collection reportedly includes the nude London hue, a deep purple nod to Paris, a passionate red for Milan and a bright fuchsia pink for NYC.

Online shoppers can reportedly get their paws on the bottles by ordering them through Asos.com, which has a partnership with the soda brand.

Check them out! We'll feel oh so more glamorous next time we make our 3am 7-Eleven Diet Coke run.
