What's a little snow?

Rihanna wasn't going to let a blizzard stop her from sporting her signature style at New York City's Rockefeller Center on Saturday night.

Much to the crowd's delight, the singer took the stage with Jay-Z in an outdoor concert that was being filmed for Carson Daly's New Year's Eve special.

And instead of bundling up in a parka (as Jay-Z did), the fashion-forward performer donned a belly-baring, cropped lace corset. Brrrrr!

If the scantily-clad style has you shivering for more, RiRi did throw some sensible winter wear into the mix -- she "covered" up in a furry white jacket (albeit, tiny and worn open), gray pleated trousers, snow-ready combat boots, long black gloves and a whimsical top hat with attached veil.

Looks like Rihanna's love of corsets is translating into big bucks at the cash register. Corset sales are up thanks in part to the pop star.
