Rihanna – Celebrity Wardrobe Malfunctions

Unlike most of the celebrities on this list, Rihanna had to know that her nipples were on full display when she stepped out in this lace bandeau top for some shopping in Soho.

Dark skin + pale pink, sheer fabric - a bra = wardrobe malfunction. We can't imagine why one of her friends didn't step in for a fashion intervention ("Ri, you look cute, but I can see like, 100% of your nipples."). It's not like Rihanna really seemed to care, though -- the 'S & M' songstress likes to take off her top more than a drunk college girl on spring break.

If you wanna see Rihanna's nipz fo real, you can see a NSFW pic here. We bet the Bajan stopped traffic with those headlights! *ba-dum-tss*
