Rihanna in Brazil

Though no stranger to baring her breasts in see-through shirts, Rihanna had a bit of a nip-slip during her current trip to Brazil, and accidentally revealed the new spikes she has for her nipple piercings. She also took to Instagram to debut her new long hair (above)! Love it! Check out the wardrobe malfunction in the gallery.
