Rihanna: It's Nippy Out in New York!

As if she couldn't be any more overexposed, pop diva Rihanna decided to let it all hang out and roamed the streets of New York City in some sort of a see-through, pink, lacy, strapless bra top thing on Monday afternoon.

The 24-year-old "Birthday Cake" singer kept the sexy lingerie as outerwear theme and even rocked what appears to be some sort of ruffled slip as a skirt.

When you're as cool as RiRi, anywhere can be a Victoria's Secret runway.
