Barbadian musician, Rihanna, is so full of surprises and we just love to see her latest antics whenever she displays them.

The daring singer who is currently having a good time in Brazil, shared this photo of herself and a friend who seems to be fondling her boob (or perhaps just trying to adjust her sarong).

She also shared other hot photos while chilling on a luxury yacht on the Caribbean sea.

The multi award-winning artiste recently posed topless for a Vogue magazine shoot, on a beach in Rio de Janeiro, Brazil.
