Are These Rihanna Bikini Photos Her Hottest Ever?


It may be the dead of winter in Canada but for celebrities like Rihanna, it's summer year-round.

The "Stay" singer made us envious when she posted some sexy bikini photos on her Instagram Thursday, which was part of a photo shoot taking place in Brazil.

The 25-year-old didn't caption her pics (we get it, no words were necessary) but we got the idea that she was generally having a good time relaxing in a tiny black two-piece which showed off her multiple tattoos and her lean physique.

But, realizing that one bikini just wasn't enough, the bad girl changed into a sexy g-string one-piece which showed off her shapely behind and toned legs.

With all the fun Instagram pics, it seems as if RiRi has been on a permanent vacation since wrapping up her Diamonds World Tour last November.

Fortunately, the singer has kept busy doing controversial photo shoots, posing for Balmain's Spring/Summer 2014 campaign and making us envious of her beach parties.

Keep doing your thing, girl!
