Rihanna in See-Through Top Pictures

Rihanna Shops in a Racy Top as Her Nude Billboard Goes on Display

Rihanna shopped in NYC.

Rihanna caused a stir in NYC yesterday while shopping. She stepped out in a see-through bandeau top, which was paired with a matching skirt. Click through to see more photos of Rihanna in the Big Apple, but please note some photos are NSFW. Her racy top got a few looks from fans on the street, and she's also turning heads thanks to a new billboard in Times Square. Rihanna posed nude for an ad promoting her fragrance Rebelle.

She's been showing lots of skin lately, and some friends are concerned — a current report suggests her pals want Rihanna to slow down the breakneck schedule that's seen her hospitalized twice in recent months for exhaustion. Rihanna laughed off rehab stories, though, firing back with an Instagram photo. Rihanna's clearly a major star, and is among the hottest celebs in this year's PopSugar 100!
