Rihanna‘s smoking, taking off her clothes and, you know, just being Rihanna in her latest Instagram shots.

The “We Found Love” singer shared the latest series of new bikini pics from Brazil on Wednesday, Jan. 22, showing off her hot bod in a tiny two-piece alongside a female pal.

The ladies, both clad in red swimsuits, puff away on cigars as they pose for the cameras, and in one particularly provocative shot (taken from behind), Rihanna can be seen untying her bikini top to remove it completely.

These sexy snaps are just the latest shares from Rihanna’s scantily-clad trip to South America. Earlier this week, she posted not one, but 14 sexy pics of herself in a gold string bikini. She also wasn’t shy when it came to Instagramming topless pics of herself chillin’ aboard a yacht! (Shy and Rihanna are rarely in the same sentence though, let’s be honest.)

The 25-year-old is currently in Rio currently in Rio de Janeiro for a Vogue Brazil photo shoot. Judging from what we’ve seen so far, she won’t be wearing a whole lot of clothing in the mag, but hey, skin is in!
