Rihanna flaunted her figure in a tiny two-piece while swimming in Israel's Dead Sea last week. She appeared to be posing for a photographer during her dip but still made time for a quick soak in the notoriously salty waters before showering off. True to form, Rihanna later shared the sexy snaps on Instagram, though her visit to the famous sea resulted in the singer reportedly being more than two hours late for her concert in Tel Aviv that night. Rihanna, who is currently traveling the globe as part of her Diamonds World Tour, is heading to San Juan, Puerto Rico, for a show on Tuesday night before hitting the stage in her home country of Barbados. In addition to performing and taking in the world's natural wonders, Rihanna made time to give a birthday shout-out to her BFF Katy Perry last week. She posted a collage of photos of the two, saying, "Happy Birthday to my lover and friend!! I miss you so much!!"
