Rihanna posts nearly naked 'Nude' fragrance ad photo: What does RiRi smell like anyway?

Rocking blond hair, a bra and little else, Rihanna wants you to buy what she's selling in the ad for her new fragrance, Nude.

"Here is my new ad for a brand new fragrance #NUDE !!! Make sure you smell sexy, especially naked, this fall," the possibly on-again girlfriend of Chris Brown tweets Friday (Oct. 5) along with an Instagram pic of the ad.

When a follower askes RiRi to describe Nude's scent, she writes back, "ME!!!"

And as for the meaning behind the name of the perfume, Rihanna has this to say in 140 characters or less: "it means u don't need to wear anything else."
