Rihanna’s sexy swimsuit tour of Hawaii continues! The “S&M” singer once again took to her Twitter to post some silly-sexy pics of herself in a teeny bikini. 

RiRi, 23, tweeted six photos, one of which had her on an elliptical with a caption that read simply: “#SNAP.” Another caption read: “Strike a POSE.”

This is the second sexy swimsuit we’ve seen the outrageous pop star in since hitting Hawaii. 

RiRi swam with the sharks wearing a silver monokini that was so skin-baring that she had to tweet out a pic. The singer wrote: “Swimming with Sharks is one of my favorite things I’ve ever done.”
